Officials at a state laboratory reported to police Friday that DNA from a rape that happened in late January or early February matched Mixon's, said Lt. Kevin Wiley, who oversees the police sex crimes unit.
Mixon's DNA was on file because of his conviction in 2002 for assault with a deadly weapon in an attempted carjacking in San Francisco, for which he served six years in prison. The state lab's match was reported Friday afternoon to an Oakland police sex crimes investigator, Officer Herb Webber, Wiley said.
Webber got the news shortly before leaving work at his scheduled time, Wiley said. Police could not have issued an arrest warrant immediately for Mixon because investigators first would have needed to gather another sample of his DNA for comparison purposes, the lieutenant said
