Costilla shooting: Trial postponed, plea deal underway


A plea agreement is in the works for Andrew Bernard Mott, a Costilla man accused of firing a handgun at a New Mexico State Police officer and his family in March.

Details of the agreement were not publicly available as of press time Wednesday (Oct. 18).

Mott is facing four aggravated assault charges connected to the alleged event, which took place along a dusty county road just south of the town of Costilla near the Colorado border.

An arrest warrant was issued for Mott in March after State Police Lt. Jose Martinez reported that Mott had fired what appeared to be a handgun at he and his family as they drove down County Road B-050 to visit a newly constructed rodeo arena near Mott’s residence. Mott allegedly confronted the family in the roadway, got out of his vehicle and yelled obscenities at them before brandishing the firearm and taking one shot that passed over the vehicle, according to court records. A police report indicates that Mott had raised the firearm before discharging the weapon. No one was injured during the event.

Mott was arrested during a high-profile state police tactical operation two weeks later and was incarcerated in the Taos County Adult Detention Center. In April, he was granted a conditional release, which required the defendant to turn in any firearms in his possession. According to court records, he turned over a .50-caliber sniper rifle and an assault rifle before his release, but the .45-caliber handgun police believe he may have used during the alleged crime was not turned in, according to the most recent updates.

A plea conference is scheduled for Oct. 31, a Tuesday, in Taos District Court, Courtroom A.
