Sacramento authorities arrested man suspected of committing a series of violent sexual assaults using DNA technology and genealogy websites to identify him
SACRAMENTO, Calif .– A man suspected of raping women near Sacramento freeway interchanges several years ago has been arrested after investigators used DNA technology and genealogy websites for the locate.
JD Wallace Simien, 40, was arrested Thursday and charged with kidnapping, rape, oral copulation and robbery, according to prison and court records.
The investigation remained cold until detectives used the same DNA genealogy techniques to identify and capture Joseph DeAngelo, known as the Golden State Killer, and Roy Waller, the so-called “NorCal Rapist” who was convicted. last year for raping nine women in their homes.
“DNA technology is a great tool in our criminal justice system,” District Attorney Anne Marie Schubert said in the statement. “DNA can not only be used to exonerate innocent people, but it is a powerful investigative tool for violent crimes that have become cold because traditional investigative methods are unable to resolve the case.”
Deputy Chief District Attorney Rod Norgaard declined to release further details of the case, including the number of victims and dates of the crimes, citing the ongoing investigation. A complaint was due to be filed on Monday, when Simien is due to appear in court for the first time.
It is not known if Simien has retained the services of a lawyer to speak on his behalf.
DeAngelo, a former police officer who committed 13 murders and dozens of rapes, escaped capture for decades before the district attorney’s lab used DNA from crime scenes to compare it to DNA provided to a genealogical website. He was convicted and sentenced last year to life in prison without parole.
Waller was sentenced last year to 897 years in prison – the maximum allowed by law – for raping nine women in a 15-year wave of crimes that began in 1991.
