CHICAGO (CBS) — A Southwest Side business owner was murdered Friday, and police are looking for his killer.

CBS 2’s Jeremy Ross reports.

Chicago police squads drive in and out of a place used to vehicle traffic. For a time, LL Pena Trucking Inc. — at the corner of Keating and 43rd — saw more investigators than trailers.

Neighbors say cops began gathering about 9:30 a.m. Friday.

The victim was Louis Pena, 64, according to the Cook County Medical Examiner’s Office. Workers say he was the owner of the trucking company; a source tells CBS 2 the victim was shot in an office trailer on the property.

Police say the victim was shot in the head twice and pronounced at the scene.

The victim is described as a family man, and a hard worker spending long hours at the business.

Police say no one is in custody.
