OAKLAND -- A 55-year-old Oakland man was convicted Tuesday of killing an Oakland woman in 1987, a murder that was solved with DNA technology 25 years after the fact.

Eddie Brown, also known as Eddie Joe Brock, pleaded no contest to first-degree murder in the July 10, 1987, slaying of 28-year-old Roshun Broadnax.

Broadnax's body was found partially clothed and wrapped in a carpet behind a garage in the 1900 block of 47th Avenue. She had been strangled. Officers at the time received an anonymous tip that Brown was responsible, but they couldn't find enough evidence to arrest him, Alameda County deputy district attorney Jason Chin said. Brown had scratch marks on his face when he told detectives that he didn't know Broadnax and had no physical contact with her, according to court documents.

Oakland police reopened the case in 2012 and submitted a profile of DNA found under Broadnax's fingernails to the state database of convicted felons.

Once the DNA was matched to Brown, a registered sex offender, he was arrested and charged with murder in the course of a rape, punishable by life in prison without the possibility of parole.

Prosecutors on Tuesday dismissed the rape special allegation as part of a plea deal. Brown will be sentenced Sept. 4 to 25 years to life in prison. His attorney declined to comment to reporters.

Chin said he would not comment on the facts of the case, including whether Brown knew the victim, before sentencing.

Court records show that Brown has 1979 convictions out of Santa Clara County for assault with intent to commit a sex crime and second-degree commercial burglary,

Modern California law states that a convict sentenced to 25 years to life would have to serve 25 years in prison before he is eligible for parole. Because the murder Brown committed was in 1987, his case will follow laws from then, meaning he will be eligible for parole in 12½ years.
