Police are investigating after a man was shot during a robbery at his southwest Houston home.

Around 9:45 p.m. Tuesday, police said two suspects entered a home in the 5000 block of Mackinaw through an open door in the attached garage. A witness told police those two men were inside for a minute or two, then suddenly ran out, jumped in a white vehicle and sped off.

Police said the witness contacted the victim's roommate, who had run to the store. When the roommate arrived, he found the victim shot once.

Friends of the victim identified him as 27-year-old Adriano Diaz.

Officials said Diaz was in the shower when he was shot. He was taken to the hospital, where he was pronounced dead.

No arrests have been made.

Anyone with information about this shooting is asked to call Crime Stoppers at 713-222-TIPS.
