OKLAHOMA CITY –  Police are investigating a home invasion that turned into a homicide at an apartment complex in southwest Oklahoma City.

Police responded to the Almonte apartments in the 5900 block of S. May just after 1 p.m. Monday.

Authorities say two intruders knocked on the door of a second story apartment, and then kicked in the door.

“Reports say that the victim heard a knock at his door, he later heard kicking at his door and saw two suspects enter into his residence,” said Ashley Peters, with the Oklahoma City Police Department.

Police say the man who lives at the apartment went for his gun, firing multiple rounds at the suspects.

“The victim didn’t know who it was, he was having a hard time seeing who was at the front door, so he waited a little bit then after a few moments, he heard kicking and then that’s when both suspects entered into the residence,” Peters said.

One suspect died at the scene while the other suspect ran off and is still on the loose.

Folks who live at the complex watched as investigators combed the scene for hours, collecting evidence and interviewing multiple neighbors.

Mae Gaskin recently moved into the building across from where the shooting happened and said she isn’t used to all the commotion.

“I was hoping [for] nothing like this, God forbid,” Gaskin said. “We know how the world is. It’s not perfect.”

On Tuesday, officers released information about the alleged suspect and the victim.

Police say 26-year-old Bobby Lachez Perkins was pronounced dead at the scene. The homeowner was identified as 26-year-old Jeffery Jamal Smith, but he was not arrested and is not facing charges.

Officers arrested 25-year-old Christopher Alexander on a complaint of first-degree murder and first-degree burglary.
