A dispute among a man, his wife and their adult son ended with all three dead in Ravanna this weekend. Seventy-five year-old W. B. Sprayberry, wife Linda and son William Sprayberry, age 37, were all shot to death late Saturday night. Chief Miller County Sheriff`s deputy Toby Giles said the police have only collected two murder weapons. He said the son`s wife apparently witnessed the event and is supposed to tell her story to the police tonight. Giles said autopsies may help determine who was shot first and who fired the shots. He said the son`s wife was so distraught that she could NOT give her story when interviewed yesterday.
