A deadly confrontation on May 21, 2023, at about 2:30 a.m. began inside the HEAT Ultra Lounge at Anaheim GardenWalk and spilled into the complex’s parking structure. Officers found two victims: 32-year-old Deonte Marquis Lenin of Highland, who died of a gunshot wound, and 21-year-old Elian Tanori Arvayo of Phoenix, who died of blunt force trauma. The individuals involved did not appear to know each other before the altercation.

Anaheim homicide detectives identified 21-year-old Aristeo Martinez of Phoenix as a suspect in Lenin’s murder; Martinez was arrested in Phoenix on May 30, 2023, held in Maricopa County Jail on $1 million bail pending extradition, and charged with Lenin’s murder. Investigators continued to probe the circumstances and the separate investigation into Arvayo’s death remained ongoing as of December 2024.
