Family and friends offer tearful remembrances of a fun-loving, sensitive, caring teenager who was killed in car crash Memorial Day weekend.This was not to be a somber affair, said Elizabeth Sweet, moments before the memorial. It was to be a celebration of life, of the upbeat spirit that for so long had typified her daughter, Ashton Sweet, a 14-year-old cheerleader from Irvine who died in a violent Memorial Day weekend car wreck allegedly caused by a drunk driver.
