(RICHMOND) -- Authorities are awaiting toxicology results to determine how a 22-year-old St. Clair County woman died. Police say an autopsy Monday on Samantha Ward's body revealed no signs of foul play. Ward, of Columbus Township, was out Friday night in Macomb County's Richmond with friends at a tavern. Police say she took a different path as the group started to walk to their homes. Her body was found about 9 a.m. Saturday without a hat, jacket or gloves. Temperatures early Saturday morning were near or below zero. Police were reviewing surveillance video from shops in the area.
