FARMINGTON -- Police late Monday night found the body of a missing man shot to death in Crouch Mesa.

Police are seeking Mark Hinojos, a San Juan County man, on a warrant charging him with second-degree murder for the man's death, Farmington police Detective Sgt. Brandon Lane said Tuesday.

Sabrina Pacheco, of Farmington, and Angel Barney Mares, of Crouch Mesa, were arrested late Monday on suspicion of tampering with evidence and conspiracy to tamper with evidence in connection to the case.

It was unclear whether the victim's family has been notified.

Lane said police were called to Pacheco's Farmington apartment, at 3986 N. Butler, Sunday night after a shooting was reported.

Lane said police believe the man was shot at the apartment and then Pacheco and Mares helped transport the body to an isolated location in Crouch Mesa between Farmington and Bloomfield where police found the man's body at about 10 p.m. Monday.

He appeared to have died from gunshot wounds, Lane said.

The investigation into the man's disappearance led police to Mares' trailer at 55 County Road 5572 on Monday afternoon.

A standoff ensued for several hours between suspects inside the home and local law enforcement, including the Farmington police SWAT team.

The suspects in the trailer didn't respond to the SWAT team's request for them to leave the trailer and turn themselves in. Most of the police officers involved in the standoff left the area before two young girls were dropped of by a school bus at about 3:30 p.m.

Lane said several Farmington investigators stayed outside Mares' trailer Monday evening and they arrested Pacheco and Mares as they were running from the trailer.

Farmington detectives and U.S. Marshals are searching for Hinojos and have a warrant for his arrest.
