Houston police are investigating a fatal shooting in the parking lot of a southwest-side apartment complex.

The man was gunned down about 8:39 p.m. Thursday at the Little Nell Apartments, 8565 West Sam Houston Parkway South.

Jerome Monroe was in his garage in the complex when he saw a man running past who was being followed by three other men.

"That's when I heard three pops," Monroe said.

He peeked around the corner and saw the man lying on the ground. Monroe said he then saw a blue car near the body.

"A guy got out and shot him again," Monroe said.

He said all the men then left in the car.

Monroe did not have a detailed description of the assailants.

The fatal shooting remains under investigation. Anyone with information is asked to contact Crime Stoppers at 713-222-TIPS.
