SACRAMENTO COUNTY, Calif. (KTXL) — A man suspected of sexually assaulting multiple people in 2013 and 2014 has been arrested, the Sacramento County Sherriff’s Office said in a statement on Thursday.

JD Wallace Simien, 40, of Sacramento County, was arrested on the suspicion he assaulted at least three women across several months, at times using a stun gun to attack victims.

The suspect in these crimes had been called the “Cloverleaf Rapist” because of the crimes’ proximity to freeway entrances and exits, which resemble a cloverleaf pattern.

Simien is accused of violently assaulting each victim before raping them. In one instance a victim was incapacitated using a stun gun. Another was knocked unconscious and dragged down an embankment. He also allegedly kidnapped one victim at knifepoint.

After an initial investigation, the cases became “cold” as years passed, the sheriff’s office said.

Authorities said they used Investigative Genetic Genealogy to identify Simien as the suspect. The same technology was used to identify Joseph James DeAngelo as the Golden State Killer or the East Area Rapist and Roy Waller as the NorCal Rapist.

Simien’s family declined to speak to FOX40 on Thursday.

Anyone with information regarding this investigation is urged to contact Sacramento County Sheriff’s Sexual Assaults Office at (916) 874-3918 or email:
