Houston police say a 14-year-old boy has been stabbed to death in a strip mall parking lot.

Police say the teenager, Joseph Aguirre-Flores, was attacked late Monday night in southwest Houston.

Witnesses told police that they heard a scream then saw Aguirre-Flores running from the parking lot to a street, where he died.

Witnesses say two men also fled the scene.

Investigators are reviewing security video, but no arrests have been made.

Houston police aren't sure what Aguirre-Flores was doing in the area.
