Rhonda Ballow, 27, was found shot to death the morning of December 27, 2017, behind a business in the 2900 block of West Washington Avenue near Rancho Drive in central Las Vegas. She and a man in his fifties had been sheltering for the night in a loading-dock area; detectives believe a shooter approached after midnight and fired six to eight continuous shots while walking toward them. Both victims were beyond help when officers arrived just after 7 a.m. The coroner ruled Ballow’s death a homicide from multiple gunshot wounds.

Investigators assembled surveillance footage and witness accounts that pointed to a suspect who, according to an arrest report, told a neighbor he had killed two people behind the swap meet because one was a registered sex offender and the woman refused to leave him. That information, together with security video and statements from nearby residents, led detectives to identify 32-year-old Michael Thompson. He was arrested January 16, 2018, near the 2200 block of Sleepy Court and booked on two counts of murder with a deadly weapon; prosecutors charged him with two counts of murder soon after.

The early scene was described as stark: two people on a mattress attacked without provocation and a trail of shell casings showing the shooter’s path. Does anyone have information about Ballow’s movements that night or saw activity near the West Washington swap meet area around midnight into the early morning?
