SACRAMENTO, Calif. - Sacramento police announced that they cracked another serial rape cold case in California that was moved forward to an arrest based on DNA testing and "genetic genealogy."
The suspect in the 1990s rape cases of several Sacramento women is now behind bars said reporter Rachel Wulff.
Wulff talked to neighbors in the east Sacramento neighborhood where Mark Manteuffel lived for more than a decade. Several people told her they could not believe that their neighbor is being charged in several violent rape cases that occurred between 1992 and 1994. It turns out he was known in the neighborhood. He was a quiet guy but was known for talking with people, and for being helpful. As an example, Manteuffel reportedly helped some neighbors with the rewiring of their home.
He attended Sacramento State, and even lectured there in the fall of 1993, confirmed university officials.
Manteuffel also worked in the federal prison system as an administrator. He retired in Florida in 2014.
Police in Sacramento have said they are convinced he is the man responsible for raping and torturing three women decades ago.
Friday the FBI tracked him down at his home in Decatur, Georgia with the help of DNA that had been recovered at a restaurant.
Investigators used "genetic genealogy" in this case, which is the same technology that led to an arrest in the East Area Rapist case in 2018.
Sacramento Police Chief Daniel Hahn said, "Without our ability to use DNA and genetic genealogy we would not have this predator in custody right now. And maybe never would."
Sacramento County District Attorney Anne Marie Schubert said catching a predator like Mark Manteuffel is about passion, patience and persistence.
"I'm proud to say we have put a face to that DNA profile and today, a quarter century later, a silent witness has spoken," said the District Attorney.
Schubert praised the ingenuity and teamwork of detectives who had the foresight to keep DNA test kits longer than the law allowed at the time.
