OKLAHOMA CITY -- A man arrested in Texas after being suspected in the disappearance of his girlfriend has returned to Oklahoma.

Oklahoma County Sheriff's deputies traveled to Fort Worth, Texas and returned to Oklahoma with Ronald Banks, 34, Tuesday.

Banks was arrested Saturday night on a first-degree murder warrant in connection with the disappearance of 49-year-old Angela Biggers.

Biggers had been dating Banks for two months when she disappeared.

Biggers was last seen Monday, Dec. 6 at her workplace. Her Ford Focus hatchback was found Monday morning at an apartment complex.

An arrest warrant affidavit stated Banks made numerous phone calls to family and friends starting the day after Biggers' disappearance saying "something bad happened." He had "done something stupid," and "I didn't mean for it to happen." He reportedly told a family member that "she won't be reporting anything stolen," and "the only thing going for me is no body, no crime."

Police still don't know Biggers' whereabouts. Anyone with information about her disappearance should call the Homicide Tip Line at 405-297-1200.
