WIZARD WELLS, Texas — Editor's note: The video published above is a WFAA report about a bill inspired by a North Texas teen killed in 1974 to help solve more cold cases.
The remains of a woman found in a remote area of Wizard Wells in Jack County, Texas, back in 1984 have remained a mystery until now.
The Jack County Sheriff’s Office and Texas Rangers identified the woman Wednesday as Roberta Mumma, who was 25 years old at the time of her death. According to officials, Mumma's last known location before she was found dead in the rural North Texas town was all the way over in Tennessee.
Now, after being identified 40 years later with the help of advanced forensic techniques and DNA analysis, law enforcement officials are actively investigating the cold case and asking for the public's help with information on Mumma's homicide.
"The smallest detail could be crucial in solving this case and bringing closure to Roberta Mumma’s loved ones," Texas DPS officials said in a press release.
