Riverside police announced Thursday morning that they arrested one person and continue to search for a second individual in a series of sexual assaults and other violent crimes in Southern California.
Authorities made the announcement -- previously, investigators believed one man was responsible for the crimes -- at a Thursday news conference. Authorities said they were "surprised" to learn two people were involved in the crimes.
Maurice Jennings (pictured, right), arrested Sept. 27, is accused of robbery and sexual assault of three women in November 2008 and the robbery of two women January 2009. Most of the information that led to the Corona man's arrest became available after authorities received anonymous tips and released surveillance video of the crimes late last month, according to investigators.
But DNA collected from other crime scenes, including massage parlors and spas, excluded Jennings from those crimes. That development led investigators to search for a second attacker, connected to five other crimes by DNA evidence.
"We thought we had one suspect committing these crimes," said Riverside Police detective Rita Cobb. "But, in reality, we had two."
The second subject's identity has not been determined. Authorities are investigating whether additional attacks were committed by Jennings or the other individual (surveillance image, left).
In at least one case, a gun was displayed.
The assaults -- some of which occurred at massage parlors in three Southern California counties -- date to 2003, then ended in 2009 Investigators said more recent crimes might not have been reported.
Investigators began connecting the attacks in 2006, when Los Angeles County Sheriff's detectives looking into the assault of a massage therapist in Industry became aware of a similar assault near Fontana in San Bernardino County. Three years later, Riverside investigators submitted a sample in another case to California's Department of Justice, but were not notified of the matches until April 2012 because of a backlog in the system.
