- The Mendocino County Sheriff's Office says the body of a woman was found in Northern California river that a family's SUV plunged into last week. They say the items are consistent with a family on vacation and unspecified items were identified by relatives of the Thottapilly family.
The 100-foot (31-meter) drop killed the women, both 39, and their children Markis Hart, 19; Jeremiah Hart, 14; and Abigail Hart, 14.
Five bodies were found March 26 near the small city of Mendocino, a few days after Washington state authorities began investigating the Harts for possible child neglect, but three of their children were not immediately recovered from the scene. Were the children purposely drugged and did the parents know they were on suicide mission when they headed out for the "road trip".
