Javier Chacon, 48, was found dead at his home in the Pleasant Grove neighborhood of Dallas on August 16, 2015. Family members returned to the house around 9 p.m. and discovered Chacon with a gunshot wound; Dallas police were called and initially treated the death as a homicide.

Police determined the cause of death was a gunshot wound, but early reports left the exact circumstances and motive unclear. Investigators said they had no immediate suspects and worked the case for several months without a public breakthrough. In the weeks after the killing, 31-year-old Juan Miguel Andrade was arrested and charged with two separate Dallas murders, including Chacon’s; police reported finding .45-caliber casings at the Chacon scene and say Andrade confessed to the killings.

Anyone who knew Javier, his routines in Pleasant Grove, or who might have seen or heard anything on the night of August 16 is asked to share information with investigators.
