SAN ANTONIO -- Police say that they’ve finally captured a serial rapist almost 20 years after two sisters were raped at knife-point.
According to the San Antonio Police Department, they were able to link the sisters’ case and two other victims from two separate cases thanks to the use of a DNA database.
The suspect, Robert Acosta, claims innocence, but police say that the DNA links him to those rape cases.
In 1999, two sisters, 14 and 15 years old, were at a movie theatre near I-37 and Southcross in what is now a shopping center. Police say that Acosta pretended to be a cop and ordered the sisters in his car and raped both of them at knife-point.
“The detectives were working other cases and they got a notification of a CODIS (Combined DNA Index System) hit,” SAPD Sgt. Jesse Salame said. “That’s a national database, whenever there is any biological evidence that’s collected from these scenes.”
Police say that CODIS linked Acosta to two other sexual assaults: one in 2006 and another in 2010. And there could be others that police don’t know about yet.
“If you’ve been a victim of this individual, or any individual, any sexual assault, you need to call us,” Sgt. Salame said. “I know that’s difficult. There’s nothing to be ashamed of. We are here to help.
For now, Acosta has been charged with two counts of aggravated assault, and there are more charges coming.
There is no statute of limitations on rape, so police urge anyone who thinks that they may have been a victim to come forward.
