Michael Dalton, Illegal Firearm Possession, New Mexico 2023

Michael Dalton, 34, of Roswell, N.M., was found guilty by a federal jury Tuesday night on two counts of illegally possessing firearms and ammunition—crimes rooted in a violent, meth-fueled standoff with police three years earlier. The verdict, delivered in Las Cruces after a three-day trial and two hours of deliberation, marks the latest conviction in a federal crackdown targeting New Mexico’s most dangerous repeat offenders.

Dalton, a seven-time convicted felon, was barred from owning guns due to prior felony convictions including burglary, aggravated fleeing from law enforcement, forgery, larceny, and possession of a controlled substance. Despite that, officers from the Roswell Police Department recovered two rifles, a handgun, and approximately 240 rounds of ammunition from his Chaves County residence during a search warrant execution following an August 28, 2015, incident.

That night, a neighbor called police, reporting that Dalton threatened to shoot his girlfriend in the head during a violent argument outside his home. The caller also saw Dalton attempt to run over the woman with his vehicle before barricading himself inside with his three-year-old child. Gunshots were heard moments later. After an hour-long standoff, a SWAT team coaxed Dalton out, where he was arrested and later identified as a prohibited possessor of firearms.

The federal indictment, originally filed June 30, 2016, was later superseded to add a second charge: being a drug addict in unlawful possession of firearms. Trial evidence confirmed Dalton was a methamphetamine user at the time of the offense—further disqualifying him from legally owning weapons under federal law.

Dalton was transferred to federal custody in June 2016 after being held on related state charges, which were later dropped in favor of federal prosecution. He’s remained behind bars ever since. Under the superseding indictment, Dalton now faces up to ten years in prison on each count when sentenced at a date to be determined.

The case was jointly investigated by the ATF’s Las Cruces field office and the Roswell Police Department. Prosecuted by Assistant U.S. Attorneys Alexander B. Shapiro and Marisa A. Ong, it was brought under a federal anti-violence initiative aimed at removing chronic offenders from New Mexico communities for extended periods. U.S. Attorney Damon P. Martinez, District Attorney Dianna Luce, ATF Special Agent in Charge Thomas G. Atteberry, and RPD Chief Phil Smith all hailed the verdict as a victory for public safety.
