PASADENA : Third Person Arrested in Slaying of Couple

A third person has been arrested in connection with the slayings of a young Pasadena couple in which police now suspect robbery was the motive.

Nicholos Dwane Martin, 18, of San Bernardino, surrendered Thursday afternoon at Pasadena police headquarters, detectives said. Murder charges are expected to be filed Monday in Pasadena Superior Court.

Jeffrey Venable, 25, was found Monday suffocated in the apartment he shared with Robyn Braxton, 20, whose body was found later the same day. She had been shot and dumped beside California 38 in a remote area of San Bernardino County.

Two other men, said to be friends of the couple, were arrested Tuesday. Christopher Scott, 26, of Fontana, was released after police said they were not prepared to file charges. He has not been eliminated as a suspect, officials said. Cedric Singleton, 27, of Riverside, remains jailed for a parole violation and charges related to the murders may also be filed against him Monday, police said.
