New details emerge about how DNA led to serial rape suspect

DNA tests that linked a serial rape suspect to several attacks wasn't in the hands of police until after a wreck that left the suspect in a coma.

Tulsa police tell KRMG that after they got the name from the Oklahoma State Bureau of Investigation, a detective Googled it, and it turned up in an accident report issued by the Oklahoma Highway Patrol.

That led them to Desmond Campbell, the man they say terrorized the city, attacking at least seven women over the course of two months.

People on social media have questioned whether Campbell is actually the rapist, since his photo doesn't resemble the police sketch based on a victim's description.

But, TPD confirms that some of the DNA evidence they've matched to Campbell was recovered from the scene where that same victim was attacked.

"We know it's him," Officer Jillian Roberson tells KRMG. "We know he was at her residence that night."

OSBI had his DNA because he had two felony convictions in Oklahoma City.

Campbell crashed his car into an exit sign on I-44 near Sheridan Road early Sunday morning.

Police got the DNA results from OSBI linking Campbell to the rapes days later.

So unknown to them, as they were working hard to find their man, he was lying in a coma at a Tulsa hospital.

KRMG contacted the hospital to find out who will pay the medical expenses, but they have not returned our call.

TPD and the city aren't on the hook for the medical expenses, because Campbell hasn't been arrested.
