Marcus M. Collins, 39, was fatally shot at about noon on May 25, 2017, inside an apartment at the Shelter Island Apartments, 3770 Swenson St., in central Las Vegas. Police say Collins was at the unit with a friend, a woman, an unidentified man, and several other men when the situation escalated after Collins produced money and several men pulled out guns. Collins argued with a man later identified as Anthony Fletcher. Collins was found unconscious and shot, lying partially on a couch and without clothing; his friend had been pistol-whipped and knocked unconscious earlier.

Investigators linked the confrontation to a burglary in which two pit bulls and several pairs of sunglasses were taken. A confidential tip and information from Collins’ ex-girlfriend indicated Fletcher had seen Collins wearing stolen sunglasses and confronted him. An arrest warrant was issued naming Anthony Fletcher, 39, on charges of murder, kidnapping, and robbery, and he was taken into custody and held without bail at the Clark County Detention Center.

What details about the events inside the apartment or the other people present might help explain how the confrontation turned deadly?
