An Oklahoma man accused in California of the 1973 shotgun slayings of two girls has agreed to waive extradition and return to the state to face murder charges.

Creek County District Attorney Max Cook said Thursday that 65-year-old Larry Don Patterson waived extradition during a hearing before a judge in the Oklahoma county, which is just southwest of Tulsa.

Patterson was being held without bond in the Creek County Jail, but Cook says he believes California officials will return Patterson to the state "fairly quickly."

A law enforcement task force arrested Patterson on Tuesday in the rural town of Oakhurst, Oklahoma. Patterson's cousin, 65-year-old William Lloyd Harbour, was arrested in California.

Both men face murder charges in the deaths of 12-year-old Valerie Janice Lane and 13-year-old Doris Karen Derryberry.
