Oakley police said during a press conference on Thursday that Gabe's disappearance is now a homicide investigation and they are searching for her body. "Due to the information that has been yielded during our long and intensive investigation, I must announce at this point, that we believe Alexis Gabe is the victim of a homicide," said Oakley Police Chief Paul Beard.
Contra Costa District Attorney Diana Becton said in a Thursday afternoon press conference, that investigators and the DA's office had sufficient evidence to file criminal charges against Jones. They had phone intercept recordings, surveillance footage, cellphone data and DNA evidence.
Despite the mounting evidence linking Jones to the crime, Chief Beard says it took months to piece together the data before an arrest warrant could be issued.
