The Texas Department of Public Safety is expanding the Texas Rangers' Unsolved Crimes Investigation Program, a specialized unit dedicated to solving cold case murders and sexual assaults across the state.

"For nearly 25 years, the Texas Rangers Cold Case Program has helped partner law enforcement agencies bring justice to victims and their families in every corner of Texas," said Texas Ranger Division Chief Scotty Shiver.

"The expansion of this program is a testament to the Rangers' success in working alongside investigators and forensic scientists to identify and arrest criminals who, sometimes for many years, have believed they have gotten away with committing some of the most heinous crimes," Shiver said.
