On the morning of November 5, 2023, 22-year-old Hispanic male Maykool Regino-Perez was found in the backyard of a Las Vegas home suffering from multiple gunshot wounds. Police responded about 2:20 a.m. to a shooting call at a house party in the 1600 block of North Betty Lane; medical personnel pronounced Regino-Perez dead at the scene.

Witnesses say a confrontation began when an 18-year-old male grew upset, believing Regino-Perez was flirting with his girlfriend. That disagreement reportedly escalated into a physical altercation in which the 18-year-old allegedly punched Regino-Perez, then produced a firearm and shot him multiple times, including after he fell to the ground. One witness reported hearing five to seven shots.

Investigators recovered six .40 caliber cartridge casings from the backyard. A black .40 caliber firearm was reportedly confiscated when the 18-year-old, identified as Mauricio Quinteros, was taken into custody; he was booked into the Clark County Detention Center on a charge of open murder. Did anyone at the party or in the neighborhood see what happened or have additional information about the shooting?
