A domestic shooting in Phoenix ended with two men dead after a daytime dispute. On May 16, 2024, at about 2:15 p.m., police responding to a residence near 33rd Drive and Northern Avenue found 29-year-old Brandon Russell suffering from at least one gunshot wound. He was taken to a hospital and pronounced deceased.

Investigators say the shooting began during an argument between Russell and another man. That man, identified as 23-year-old Devin Gerrod Montgomery, fled the scene. Officers later located Montgomery at an apartment complex near 25th Avenue and Cactus Road. He ran a short distance, collapsed, and was transported to a hospital where he was pronounced dead. No officers were injured.

What details about the argument or either man’s recent movements could help explain how the situation escalated to deadly violence?
