U.S. Customs and Border Protection officials took Genaro Galvan-Mora, 26, into custody Wednesday evening near Nogales, Arizona.

A records check during processing by Tucson Sector Border Patrol agents showed Galvan-Mora was convicted in May 2016 on a reckless homicide charge in Tennessee’s Loudon County. The charge stemmed from a deadly game of Russian Roulette, according to a Loudon County newspaper and police records.

Galvan-Mora was deported on Feb. 27 after nine months behind bars, the Associated Press reported. He had been sentenced to 3 years in prison after pleading guilty, according to court records.

He was arrested on the reckless homicide charge in 2014 when he was 23, The Loudon News-Herald reported at the time.

Evidence and circumstances surrounding the case suggested that Mora and the victim, 25-year-old Diego Cisneros Fonseca, were involved in Russian Roulette by putting one round in a six-shot, .357-magnum revolver, the paper reported.

Investigators suspected Mora discharged the gun by spinning the cylinder and then pressing the gun to Fonseca’s head and pulling the trigger, the paper reported, citing police.

“Alcohol was involved. I don’t know how intoxicated they were, but they were definitely drinking,” Loudon Police Detective Brian Jenkins was quoted as saying. “Anytime you do something that you either know or should know possesses a great risk of death, it’s considered reckless homicide.”
