The suspect got away and the case went cold until detective Erik Whitlock took the case. He used new resources through DNA testing and genealogy examinations that identified the suspect from Oklahoma.
"On December 14, 2021, we were notified that this individual Mark Alan Long was believed to be the suspect associated with the DNA profiles found at three of the bank robberies at Oklahoma City and Arlington," North Richland Hills Police detective Erik Whitlock said.

Along with DNA, the investigation found Long's truck had tailgate damage from Garner firing back.
They also found the gun that matched ballistic testing.

"That weapon being found in context to him leaving it out in the interview as a weapon he owned got a lot of us excited,” Whitlock said. “That 19 years later he did actually keep the weapon he used in multiple bank robberies and to shoot officer Garner."

This was a multi-agency investigation that included the Oklahoma State Bureau of Investigations, and the Federal Bureau of Investigations Dallas and Oklahoma City field offices.

Through the investigation, Long is believed to be linked to seven bank robberies from 1998 to 2003.
