Hialeah police identify man whose body was found dismembered on train tracks

Police say William Martinez killed Boca Raton man, dismembered body

HIALEAH, Fla. – Hialeah police have released the name of a 60-year-old man whose body was found dismembered near train tracks last week. 

The remains of Jose Manuel Diaz Guerra, a Boca Raton resident who lived alone, were found scattered along the tracks west of Palm Avenue and 21st Street.

William Martinez, 40, was arrested on Thursday by Hialeah police on a second degree murder charge.

Newly released surveillance footage shows a man walking in a grassy area by the train tracks holding a plastic bag. 

Police said footage from a neighboring business captured a man throwing an object on the tracks in the area where the  remains were found.

Guerra’s body was found after detectives knocked on the door to the apartment where Martinez lives with his mother and smelled a strong odor that appeared to be coming from a decomposing body. They said they also saw a mop and cleaning materials on the floor.

Detectives said they observed a BBQ with a black cover on it that smelled like a decomposing body was inside.

Martinez's mother told detectives that her son admitted to her that he killed the victim inside the bedroom of the home, dismembered his body, and stored his body parts inside her BBQ and green garbage tank.

He also told her that he dumped body parts on the train tracks, detectives said.

Authorities believe Martinez knew the victim and that the killing was the result of an argument between the two.
