FARMINGTON — Police are looking for a man who allegedly stabbed a person at a post-prom party and then caused a roll-over car wreck on Sunday.

An arrest warrant with a $20,000 cash-only bond has been issued for Diego Mark, 18, of Shiprock, in connection to the incidents, according to a press release from the San Juan County Sheriff's Office. Mark faces two counts of aggravated battery with the use of a deadly weapon, a third-degree felony.

Sheriff's deputies were dispatched at about 6 a.m. Sunday to a vehicle wreck near County Roads 6480 and 6487 in Kirtland, according to sheriff's office detective Sgt. Candice Montoya.

While responding to the wreck, Montoya said deputies pulled over a truck driving away from the scene. The driver motioned to the deputy to approach the vehicle and said he was transporting an unidentified male who had been allegedly stabbed by Mark, according to Montoya.

The deputy called for emergency medical services, and the stabbing victim was transported to San Juan Regional Medical Center, Montoya said.

Mark had been attending a party at a home on County Road 6483 with several Kirtland Central High School students when he allegedly became involved in an altercation, pulled out a knife and threatened people, according to the press release.

He allegedly stabbed one of the male party-goers in the abdomen, and the victim fell after he was stabbed, striking the back of his head, according to police.

The victim was treated for a stab wound to his left abdomen, a wound to the back of his head and a cut under his right eye, the press release states. He has been released from the hospital.

After that, an unidentified female left the house in her car, and Mark followed her, tailgating in his truck and driving erratically, according to the press release.

When the female made a left turn, Mark allegedly rammed her car from behind. Montoya said deputies investigating the crash believe the vehicle rolled over after being rammed,

The stabbing victim showed up at the wreck and checked on the female, who advised him to go to the hospital because he was bleeding badly, according to police.

The female driver was treated for minor injuries and whiplash and has been released from the hospital.

Mark was reportedly driving a 2006 white Ford truck with a New Mexico license plate that read MGY168.

Anyone with information about the incident is asked to call non-emergency dispatch at 505-334-6622 or San Juan County Crime Stoppers at 505-334-8477.
