LAS VEGAS, N.M. — Four years and five competency evaluations after he was arrested on a charge of murder in 2017, Richard Griego is still being evaluated for his competency to stand trial.

Griego is accused of throwing Jimmy Griego, 37, off the bridge over the Pecos River on March 28, 2017, an allegation backed up by data from an ankle bracelet he was wearing for a separate case, and an eye witness account, according to an affidavit for an arrest warrant.

Richard Griego was bound over to District Court on charges of first-degree murder and tampering with evidence on May 1, 2017. His case has essentially placed on pause since Nov. 15 2017, when competency was first raised as an issue.

According to the log of a Dec. 23, 2020 hearing, prosecutor Thomas Clayton said stipulating to Richard Griego’s lack of competency to stand trial would be “imprudent.”

Defense attorney Todd Farkas said the main question on competency is Richard Griego’s ability “to assist,” presumably in his own defense.

In New Mexico, a competency finding requires three things of a defendant, according to State v. Flores (2005):

  1. Understand “the nature and gravity of the proceedings against”
  2. Have a “factual understanding of the criminal charges”
  3. Be “capable of assisting in his own defense”

District Judge Gerald Baca ordered Griego be sent to the New Mexico Behavior Health Institute in Las Vegas to be further evaluated.

In a Nov. 18, 2020 hearing, Farkas told the judge that Griego had previously been found not competent to stand trial and Clayton said it was the fifth evaluation. Two prior evaluations found him competent while three, including the only recently completed, found him not competent.

Griego has two other cases pending against him, both of which happened after he was jailed in the murder case, and both of which are rolled into the broader competency proceedings.

The first, from Aug. 3, 2018, resulted in two counts of possession of a deadly weapon by a prisoner. The second, on March 1, 2019, resulted in a charge of aggravated battery with a deadly weapon.

No new court dates are set.

Possession of a deadly weapon by a prisoner

Las Vegas Police Officer Caleb Marquez wrote in an affidavit for an arrest warrant that he was sent to the San Miguel Detention Center on Aug. 3, 2018, for a report of a prisoner who has a weapon.

Jail staff told Marquez they found several items on Griego “during a shakedown of a housing pod.” The items were a hollowed-out bolt with a nut that had a nail pushed through the hollow end, about 4 inches in length, described as a shank, Marquez wrote. The second item was a handcuff key.

Clayton filed a criminal information on Oct. 19, 2018 in district court charging Griego with two counts of possession of a deadly weapon by a prisoner.

Aggravated battery

Las Vegas Police Officer Estevan Martinez wrote in an affidavit for an arrest warrant, on a charge of aggravated battery, that he was called to the San Miguel Detention Center on March 2, 2019, for a report of a fight involving Griego and Johnny Gallegos.

Martinez wrote that he watched a surveillance video from the incident and in it, he saw the two men got into a fight and Griego pushed Gallegos out of their cell and into the hallway with a crutch. Griego then allegedly beat Gallegos in the head and back with the crutch as Gallegos crawled away on his hands and knees. On the third strike, the crutch broke and Griego kept on hitting him with it, a total of eight times.

The two men were fighting after Gallegos tried to inject a crushed pill, he wrote.

On April 16, 2019, Clayton filed a criminal information in district court charging Griego with a single count of aggravated battery with a deadly weapon.

Richard Griego’s competency questioned by his attorney; case likely to be placed on hold

See the full case write-up here

LAS VEGAS, N.M. — Richard Griego‘s first-degree murder trial will likely not go to trial on Oct. 7, 2019, the date it had been scheduled for, after his attorney filed a motion questioning his competency to stand trial.

According to a public docket for the case, attorney Todd Farkas filed a “Notice of Competency Issue and Motion to Stay Proceedings” on Sept. 11, 2019.

Richard Griego

Farkas’ notice and motion come exactly one year after the case started moving toward trial after it was placed on hold the first time for the same issue.

On Sept. 11, 2018, according to the docket, an order was entered lifting the stay previously imposed on the case after the issue of competency was withdrawn by Farkas.

The case had been functionally paused the first time on Nov. 15, 2017, when Griego’s competency was officially questioned for the first time, although minutes from status hearings note that the attorneys and judge were aware that competency may be an issue.

  • Charges: First-degree murder, tampering with evidence
  • Status: Pending; stayed for competency
  • Date of incident: March 28, 2017
  • Investigating Agency: State Police
  • Location: Pecos River Bridge, State Route 3, Ribera, San Miguel County
  • County: San Miguel
  • Magistrate case number: M-48-FR-201700095
  • District case number: D-412-CR-201700129

  • District Judge: Gerald Baca


On March 28, 2017, Richard Griego allegedly threw Jimmy Griego, 37, off of a bridge over the Pecos River on State Road 3, an allegation backed up by data from an ankle bracelet Richard Griego was wearing from a separate case which tracked his movements via GPS, according to court filings.

On May 1, 2017, Richard Griego was bound over to District Court on charges of first-degree murder and tampering with evidence following a preliminary examination. On Nov. 15, 2017, his competency to stand trial was raised as an issue and proceedings were stayed until Sept. 11, 2018, when the Notice of Competency Issue was withdrawn.

A year later, on Sept. 11, 2019, competency was again raised as an issue and the case has been stayed.

The incident

On March 28, 2017, Beverly Quintana called 911 to report that someone dumped a body off of the bridge over the Pecos River, on State Road 3, and the dumped person was her cousin, State Police Agent Patrick Montoya wrote in an affidavit for an arrest warrant.

Quintana told Montoya that she was driving south when she passed a white Ford truck heading the opposite direction. She described the driver as being angry.

Richard Griego

“As the pickup continued passed (sic) her, she noticed a male in the bed area of the pickup,” Montoya wrote. “She recognized the male in the bed of the pickup as her cousin, who she identified as Jimmy Griego.”

Quintana kept the truck in her rear view mirror and she watched as the truck stopped. Her cousin was on his knees in the back and he appeared to be terrified.

The driver pulled over and stopped on the bridge, got out and walked toward the back of the truck with someone in his right hand.

Quintana then turned around and drove back toward the truck and watched as the man, allegedly Richard Griego, carried her cousin on his shoulder, walked to the edge of the bridge and threw him over, to the river below.

When she stopped, got out, and looked down, she saw her cousin’s body floating in the river and blood on the back of his shirt. She then recognized the driver was Richard Griego.

The agent then learned that Richard Griego was on probation and required to wear an ankle monitor with a GPS unit in it. The tracking device allegedly placed him at the river at 4:18 p.m., the day of Jimmy Griego’s death.

Quintana called 911 two minutes later at 4:20.

“A Field Examiner for the Office of the Medical Investigator found blunt force trauma and two lacerations to Jimmy’s head,” Montoya wrote. “I observed the injuries to Jimmy’s head, including an indentation to the left side of his head.”

He was charged with an open count of murder and tampering with evidence, according to the docket.

On April 6, 2017, a waiver of time limits was filed and a preliminary hearing was set for May 1, 2017.

Las Vegas Magistrate Judge Christian Montaño held a preliminary hearing on May 1 and bound over Richard Griego on charges of first-degree murder and tampering with evidence. On May 19, in District Court, Richard Griego’s attorney Todd Farkas filed a motion in District Court to waive the arraignment and to enter a plea of not guilty.

Jail recordings

According to a Dec. 11, 2018 motion filed by prosecutor Thomas Clayton, Richard Griego made multiple phone calls while he was in jail that he wanted admitted as evidence.

In a May 1, 2017 call, he allegedly told his mother that someone else wanted to borrow his truck, that “those weren’t even my shoes and I wasn’t driving my truck.” His mother responded that they should not discuss “this stuff” on the phone.

Clayton wrote that the truck is an issue because Quintana saw him in his truck, on the bridge with the victim. A shoe print was also taken from the crime scene and it is a similar pattern to one seized from his house.

In a June 6, 2017 call, he talked to his mother about conversations with his attorney about getting out on bail.

“I feel this even more leaning towards, if I could get this to a justifiable homicide by citizen, protecting myself and family and property from all these conspiracies against me and stuff, will that make it easier to get a bond,” Clayton wrote, quoting from Richard Griego’s call.

In July 24 call, Richard Griego allegedly told his mother he could “beat these charges” because he didn’t “do” them and that he never hit Jimmy Griego with a weapon, but he didn’t want him “to come back and try to kill me, but he could have crawled out of the water and fucking not died. And let me alone. But no, they do, they do all this stuff. It’s all their fault that this stuff happened. Not my fault.” Clayton wrote, quoting Richard Griego.

Competency raised the first time

On Nov. 15, 2017, competency was formally raised in a written motion for the first time by Farkas. In an order on the same date, District Court Judge Gerald Baca wrote that Richard Griego had been found “in-competent” by Dr. Susan Cave and that the proceedings would be stayed pending a determination on his competency and the issue of his dangerousness.

According to notes from the June 14, 2017 status hearing, Farkas notified District Judge Gerald Baca has a documented history of mental illness and he needed to be assessed.

During a Aug. 16, 2017 hearing, prosecutor Thomas Clayton told Baca that Richard Griego sent a letter to State Police officers about an unrelated homicide, a theft and that there were also jail recordings he wanted the psychologist to listen to and that he agreed that he “may have mental issues,” according to the notes.

During an Oct. 11, 2017, hearing, Baca told the attorneys he was concerned about the discussions of competency when no motion about competency had been filed. Farkas replied that he was waiting for a report on his mental health, according to the notes.

On Sept. 11, 2018, Baca ordered that the case would start moving forward because Richard Griego’s attorney had withdrawn his claim that his client was not competent to stand trial. Farkas did not file a motion but a hearing on competency had previously been held on Sept. 7, 2018, and the records of that hearing were sealed.

No-bail hold lifted

On Aug. 1, 2018, Baca ordered Richard Griego be released if he could post a $50,000 cash bail and into the custody of a third party.

Prosecutors did not contest that finding until Sept. 25, when Clayton filed a motion for pre-trial detention.

“Upon information and belief, the family of the defendant has raised the funds to post the bond,” Clayton wrote.

On Aug. 3, 2018, Richard Griego was charged with two counts of possession of a deadly weapon by a prisoner, specifically, a handcuff key and a “nail/bolt like device approximately 4 1/2 inches in length,” he wrote.

Baca then held a hearing on Oct. 2, 2018 and ordered Richard Griego be held without bail pending trial, according to notes from the hearing.

Competency raised second time

Richard Griego’s case was placed on hold a second time, on Sept. 11, 2019, after his attorney raised the question of his competency to stand trial a second time, according to the docket.

According to the docket, the case had been set for a trial on Oct. 7, 2019 in the San Miguel County Courthouse.

A docket call was set for Sept. 25, 2019 and the judge issued an order staying the case, according to the docket.

  • Suspect: Ruth Rivera, 54
  • Victim: Arthur River, 81
  • Charges: First-degree murder, tampering with evidence, embezzlement over $20,000 and two counts of forgery over $20,000.
  • Status: Dismissed after Ruth Rivera committed suicide before she was set to plead guilty
  • Date of incident: Dec. 28, 2016
  • Agency: State Police
  • Location:  580 State Road 3 in Ribera, San Miguel County
  • Magistrate court number: M-48-FR-2017-00001
  • District court number: D-412-CR-201700044


Arthur Rivera’s daughter-in-law, who was also his caretaker since 2011, allegedly stabbed him 20 times, 15 in the body and five to the head.

Ruth Rivera claimed her father law law, Arthur Rivera, 81, had fallen in the bathroom.

According to the criminal information filed Jan. 31, 2017 in San Miguel District Court, Ruth Rivera allegedly stole $79,300 from Arthur Rivera between June 28, 2016 and December 28, 2016.

Rivera had been scheduled to to take a plea on Oct. 1, 2018, but she was found dead before then from what authorities said was a suicide.

The incident

On Dec. 28, 2016, Ruth Rivera called 911 and said her father-in-law had fallen and she needed help getting him up. When El Pueblo Fire Department firefighters got to the trailer, they found it was filled with smoke and started opening the windows. They found Arthur Rivera on the ground in the bathroom, with a large amount of blood around his body. They covered him with a blanket, State Police Agent Hector Vacio wrote in an affidavit for an arrest warrant.

Ruth Rivera had been Arthur Rivera’s caretaker since 2011. She had experience taking care of her elderly father before he died, but she allegedly described not wanting to take care of her father-in-law.

Ruth Rivera

“NMSP Officer (M.) Velasquez observed a stove inside the residence, which appeared to have damage from an explosion/fire,” Vacio wrote.

Vacio then spoke with Richard Bodell and Edward Madrid who responded to Ruth Rivera’s 911 call. They said there was a lot of smoke in the house and they had to open the windows.

Just before midnight the same day, Vacio went to the Christus St. Vincent’s Regional Medical Center in Santa Fe to speak to Ruth Rivera.

“Ms. Rivera advised she went to work at her father-in-law’s residence since she is his primary caretaker,” Vacio wrote. “Ms. Rivera made breakfast for him and later in the day she remembered him going to the restroom. As he was in the restroom she was cooking food on the stove.”

She allegedly told Vacio that she went to the bathroom after she heard a crashing or thumping noise from the bathroom.

“Ms. Rivera explained the door to the restroom was closed and she began pounding on the door but didn’t know if Arthur was hearing her,” Vacio wrote. “She stated she heard Arthur say ‘ayudame’ (‘help me’) and she went inside the restroom using another door via the closet.”

Inside, she allegedly said she saw Arthur Rivera on the ground with his head near the toilet and blood coming from his mouth. She allegedly tried to pick him up but found that she could not.

“Ms. Rivera left the residence and went to the street to flag individuals down in order to assist her to pick Arthur up,” Vacio wrote. “She does not remember turning the stove off and when she went back to the trailer there was smoke inside of the trailer.”

Vacio asked for River to hand over the clothing she had been wearing that day, which she did, in two plastic bags. Vacio noticed the clothes were damp and he wrote that this meant it appeared someone tried to remove “biological samples/stain” from the clothing by washing or wetting them. Her shirt was missing from the bags.

“The paramedic also observed Ruth Rivera’s clothes were damp,” Vacio wrote. “It is reasonably believed that Ms. Rivera washed/removed any biological samples/stains she had with intent to remove/destroy evidence.”

After getting a search warrant, the State Police Crime Scene team scoured the trailer. and found a silver knife blade and separately, on the stove, the knife handle. Both appeared to have blood on them.

When they first examined Arthur Rivera’s body, they found 17 wounds on his upper chest, face and head.

Later, at the autopsy on Dec. 30, 2016, a pathologist found 15 stab or “incise type” wounds on the man’s upper body and five stab or incise wounds to the head. There were another three incise wounds on his left hand, consistent with defensive injuries.

The following day, Dec. 29, 2016, Vacio spoke to Rivera again.

Ruth Rivera allegedly said didn’t really want to take care of her father-in-law but did so anyways.

She allegedly said in the second interview that she arrived at the house between 9:15 and 9:30 a.m., put groceries away, and cooked breakfast for him. After reading the newspaper and watching TV for two hours, Aruther Rivera went to the bathroom.

Again, she allegedly said she heard the thump or crashing noise and went to the bathroom through the closet.

“Ms. Rivera stated she placed her arns under his armpits and he began to put his weight on her and grab her by the shoulders,” Vacio wrote. “Ruth opened the other restroom door when she started smelling what appeared to smoke from the fire. Ms. Rivera stated she called 911 from her living room. The 911 call was received at 12:41 pm.”

Vacio told her that statement, different from her first that he was on the ground in a pool of blood, was not consistent with the evidence found at the scene. He told her to tell the truth.

“Ms. Rivera stated he was hurting her and he wasn’t understanding that she was trying to help him,” Vacio wrote. “She explained he was hurting her shoulders and back. Ms. Rivera stated she tried to run away from him and began to panic.”

Vacio initially charged her with an open count of murder and tampering with evidence.
