A 55-year-old Long Beach man is now behind bars after modern DNA testing linked him to a 1990 robbery and sexual assault in Oxnard, according to authorities. Investigators say the decades-old case was pulled from the shelf after preserved evidence was re-examined using forensic tools that simply did not exist at the time of the crime.
The Ventura County Sheriff's Office announced the arrest of Bobby Rollins Jr. Prosecutors allege that in 1990 he approached an 18-year-old woman as she sat parked in her car, pulled her out at gunpoint, robbed her and forced her down an embankment where she was sexually assaulted. The woman managed to drive away but crashed into a light pole about a half-mile from the scene, where bystanders stepped in to help until officers arrived. District Attorney Erik Nasarenko credited investigators' persistence and advances in DNA science for finally generating a solid lead that led to Rollins' arrest, as reported by CBS Los Angeles.
How Investigators Say They Cracked The Case
Detectives say the key was evidence collected back in 1990 and carefully stored for years. That material was later retested with newer DNA techniques that can pull usable genetic profiles from samples that are old or degraded. Investigative genetic genealogy and cutting-edge lab work have now become standard tools for Ventura County cold case detectives, giving dusty files a second life.
Local reporting has already highlighted a similar DNA twist in a 2014 Oxnard park killing earlier this spring, underscoring how carefully preserved evidence can be re-examined with modern methods to unearth new investigative leads.
Charges And The Statute Of Limitations
Rollins is currently charged with kidnapping for robbery. Prosecutors say he faces special allegations that include use of a firearm, great violence and victim vulnerability. Officials also note that the statute of limitations blocks them from filing a sexual assault charge in this particular case, despite the underlying allegations.
Investigators are still trying to identify a second person who they say was with Rollins during the 1990 attack and may be tied to other similar incidents in the Oxnard area between 1989 and 1992. Anyone who might have information is urged to call the Ventura County District Attorney Investigator at (805) 477-1638, per CBS Los Angeles.
What Happens Next In Court
The case will now move through the Ventura County court system while detectives chase down additional leads and witness accounts. Details on Rollins' arraignment date or bail status were not immediately available. Officials emphasize that long-term evidence preservation and renewed forensic scrutiny are what make these late-breaking identifications possible, even when a case is old enough to remember cassette tapes.

Cold Case DNA Wave Hits Oxnard
Authorities say this arrest tracks with a broader trend in Ventura County and across the country, where cold case units are leaning on modern DNA testing and genealogy to reopen files that sat dormant for decades. Prosecutors and local journalists note that these methods are finally delivering answers to survivors and families long after the original crimes. The April Oxnard case, involving a father killed in a 2014 park slaying, is one recent example of that shift in action.
