A woman who fatally shot her 7-year-old daughter told police she was aiming at her husband but missed, authorities said. First-grader Robin Haynes died before paramedics arrived at the family's home. Her mother, Nancy Haynes, 42, was being held in the Riverside County Jail pending arraignment. The child apparently died from a single gunshot wound, said Riverside County Sheriff's Lt. John Gillis. Sgt. Bob Saniga said Nancy Haynes told investigators she was trying to shoot her husband, Robert Haynes, 55. She said she fired the weapon and missed. The youngster, walking on the stairway landing near the front door of the master bedroom, was struck once in the upper body.
