Irbin Lopez was 20 when he was shot and killed on September 24, 2012, in Houston, Texas. He was found deceased from gunshot wounds after police responded to reports of a shooting in an area with ongoing violent crime. Investigators said his death may have been linked to local gang activity.

The city’s homicide count had risen that year, a backdrop that investigators say complicated efforts to develop enough leads to solve some cases. Despite appeals for public assistance and continued investigative work, no suspects had been publicly identified or apprehended in connection with Lopez’s killing.

If anyone has information that could help bring closure to Irbin Lopez’s family, please share it with the Houston Police Department.
