Manuel Cervantes, 37, was found dead on May 27, 2009, on Houston’s southwest side. Authorities determined his death to be a homicide after discovering him in an area showing signs of violence and classed the case as suspicious and likely the result of foul play.

Houston police were unable to identify suspects or a clear motive in the years that followed. Crime Stoppers of Houston partnered with local law enforcement to offer rewards and asked the public to call its anonymous tip line with information that might lead to an arrest. Despite those efforts, investigators struggled to develop actionable leads and the case remained unsolved, one among many violent crimes that challenged the city’s investigators.

If anyone knew Manuel, his routines, or saw activity on Houston’s southwest side around May 27, 2009, please share what was seen or heard.
