On June 6th, 1982, Charlene Corporon was found dead lying on her bed with a gun shot wound to the head.
Investigators would later charged her son, Gary Corporon, with her murder.
They were told that a grand jury has dismissed the case for lack of evidence. Without that lack of evidence, the case went cold for almost 30 years.
Last April, TNT's Cold Justice helped investigators re-open the case and gave them a new perspective.
"In addition to have a resource pool of labor, and everybody being on board we were able to send things off to the lab that we needed rather fast," said Captain Richard Rooth of Matagorda County Sheriff's Office.
The team pulled new evidence from the case and presented it to Matagorda County District Attorney Steven Reis who discovered Corporon was actually indicted back in 1982, but was never taken to trial.
Reis will now ask for an indictment, and is investigating why Corporon was never taken to trial.
