PICTURED: Grandmother, 66, who was stabbed to death by Hispanic man, 23, who also killed her dog in a random attack in a LA park 

A 23-year-old man has been arrested and charged with murder for stabbing a 66-year-old grandmother and her dog to death in a random attack in a Los Angeles park. Ricardo Saldivar is behind bars after Jeanne Edgar was found lying in Lone Hill Park in San Dimas with multiple stab wounds alongside her beloved fluffy white dog, Sashi, on Thursday afternoon. Saldivar was taken to hospital after Joe Page saw the attack and knocked him out by throwing a rock at his head in a desperate effort to stop him. 'I threw it as hard as I could and it hit him and he fell over. And at that point, I see a bunch of neighbors everywhere - people yelling,' Page told NBC Los Angeles. 'It was a horrific scene.' Source
