New Mexico State Police are looking for the Bosque Farms man charged in a car crash that killed one person and injured a State Police sergeant in October in Rio Rancho.

Dwight David Weir, 55, of Bosque Farms, is charged with vehicular homicide, great bodily harm by vehicle and possession of methamphetamine, all felonies, as well as reckless driving and a second offense of DWI, both misdemeanors. The criminal complaint was filed in Sandoval County Magistrate Court on Dec. 12.

According to the criminal complaint and State Police, Mark A. Marquez, 52, a Farmington resident and a passenger in Weir’s vehicle, was the person killed in the crash.

According to the affidavit for an arrest warrant, Weir was driving his green Ford sport-utility vehicle southbound on Unser Boulevard near Mariposa Road about 4 p.m. Oct. 22, when he crossed into the northbound lane, striking the sergeant’s vehicle head-on.

The sergeant and Weir were taken to hospitals, while Marquez was pronounced dead at the scene of the crash. The sergeant’s injuries weren’t life-threatening.

According to the affidavit, the Office of the Medical Investigator representative found four baggies containing a crystal-like substance in Marquez’s pockets while looking for ID, and a small scale was on the floor of Weir’s vehicle.

On Oct. 24, State Police investigators spoke to Weir at University of New Mexico Hospital.

According to the affidavit, Weir told them Marquez had come to his recreational vehicle on the morning of Oct. 22 and asked for a ride to pick up a friend whose vehicle was stuck on the west mesa. Marquez offered Weir a gram of methamphetamine as payment and said his friend would give Weir money, Weir told investigators.

According to the affidavit, Weir said he snorted a line of meth about 1 p.m. and another at 2 p.m. before he and Marquez left at 3 p.m. Weir rolled the rest of the meth up in his vehicle registration and put it in his center console, he told police.

By the time they were on Unser, he felt high but not “strung out,” according to the affidavit. Weir told investigators the rear end of his SUV slide out, and he tried to correct it but instead shot into the opposite lane.

Investigators served a search warrant on Weir’s car and found a white, crystal-like substance wrapped in the vehicle registration on the driver-side floorboard, according to the affidavit.

According to the State Police investigator of the crash, there was no evidence that the rear of the SUV slid, and the damage to both vehicles was consistent with the whole front ends of each vehicle crashing into each other.

“Vehicle crashes involving death and great bodily harm are complex investigations,” State Police Officer Ray Wilson wrote in an email. “Given the importance of this investigation, if we have the choice between doing this right and doing this fast, we always choose accuracy over speed.”

About three weeks ago, Wilson said, State Police submitted their reports and evidence to the 13th Judicial District Attorney’s Office. The DA’s office approved the charges for Weir, and an arrest warrant was issued Dec. 12.

Wilson said State Police are looking for Weir and anyone with information on his whereabouts is asked to call them at 841-9256, option 1.
