ST. CLAIR TOWNSHIP, Mich. (AP) - Authorities in southeastern Michigan say autopsies have been performed on the 18-year-old woman and her 27-year-old brother killed when a massive bonfire built for her high school graduation party exploded.
St. Clair County Sheriff Tim Donnellon said the autopsies on Savannah and Christopher Blewett were conducted Monday morning but he didn't yet have the results. He says preliminary information indicates they died from the trauma, not burns.
Police say the gasoline-drenched bonfire exploded about 9:30 p.m. Saturday at the brother's home in St. Clair Township, about 50 miles northeast of Detroit. Witnesses told deputies the man drenched the bonfire in gasoline, then invited his sister to set it afire.
Donnellon says "it was mean to be a celebration that went terribly wrong."
