A woman was found stabbed to death in her San Marcos home just eight days after she and her husband collected $727,000 in California Lottery winnings, San Diego County sheriff's deputies said. Her 10-month-old son, Andrew, was at home at the time of the slaying but was unharmed. The body of Ann Marie Jenkins, 30, was found in a hallway by her husband, Gary Jenkins, when he returned home from his construction job. The woman's neck had been slashed, investigators said. The couple's lottery winnings were publicized locally, but authorities do not believe the money was a motive.
