GRAYSON COUNTY, Tex. (KXII) - In May 1994, Inga Moore was last seen in Sherman. She was supposed to be at a school event with her children, but never made it.
"The next day, she's reported missing with the Sherman police department on May 27, then on May 28th they recovered her body here at Mill Creek," said Lt. Heath Wester with the Grayson County Sheriff's Office.
Moore was shot and killed with a 25 caliber handgun.
Olga Brister confessed to the crime to police, but later told law enforcement she was threatened and coerced into confessing by Inga's husband Jerry, who she claimed was the real killer.
"Mr. Moore, Inga's husband, was having an affair with a lady named Tina Agent Fox, and Olga Jean Brister was a good friend with Tina. They were buddies, spent the night with each other," said Wester.
Brister was the only one to serve jail time, serving 20 years for voluntary manslaughter.
Lt. Heath Wester said he has been working on this case for the past year and a half.
"We have felt after reviewing the case there are potentially other suspects involved, and we want to see what we can do to bring these suspects to justice. As Olga Jean Brister went to prison, other people need to go to prison as well," said Wester.
While reviewing the case, he says the physical evidence shows there could be multiple suspects.
"She was laid or carried and put into a grave. Physical evidence shows that she wasn't dragged into the grave. So Ms. Olga, who went to prison, would not have been able to do that herself," said Wester.
Wester says Moore's family deserves to have answers after decades of not knowing what truly happened.
"I think they all knew in the back of their minds that there were other people involved, but to them, its taken 25 years to get that justice solved for them. So its been hard for them," said Wester.
