A 29-year-old Southern California man has been arrested on a felony murder warrant stemming from the mauling death of a jogger by a pack of dogs earlier this month. Los Angeles County prosecutors say Alex Jackson was taken into custody Thursday. The warrant also charges him with owner negligence. Jackson was originally arrested shortly after the May 9 death of 63-year-old Pamela Devitt, who was out for a jog when she was attacked by four pit bulls in Palmdale. Jackson was released on bail while DNA testing was conducted to determine if his dogs carried out the attack. Prosecutors say since January, authorities received at least three other reports of Jackson's dogs attacking other people. Jackson is also charged with several charges related to growing marijuana.
