Police shot and killed a man carrying an assault rifle early Thursday morning as officers were watching a vehicle they believed was used in a deadly robbery.

Police surrounded an apartment complex in the 9300 block of Skillman Street.

Around 12:30 a.m., SWAT arrived to serve a murder warrant. That’s when the men in the car began to run out. One of them was carrying an assault rifle. He was shot and pronounced dead on scene.

The altercation started from a robbery at Cafe Delicious on Lamar Street in south Dallas on Wednesday. The cafe was robbed by multiple people, and an employee was shot and killed before the robbers fled.

Dallas Morning News identified the man as 53-year-old Brian Harp.

“There’s multiple suspects. I don’t want to give an exact number, but we had at least four suspects in the earlier homicide, and there’s multiple suspects we detained tonight, so we’re still trying to piece everything together,” Sergeant Warren Mitchell told WFAA.
