Investigators say that a Little Rock man shot and killed his girlfriend before shooting himself in an apparent murder-suicide. Forty-eight year old Shedric Sabb was found dead yesterday morning with his girlfriend, 57-year-old Alma B. Kimbrough at her home by her son James Kimbrough. Police said Alma Kimbrough suffered multiple gunshot wounds and Saab had at least one gunshot wound to his head. Police found him sitting on a couch next to a black handgun. Neighbors said the pair argued frequently and police said although they could not establish a motive, the two had been in an "on-again, off-again" relationship.
