CLEVELAND AP – FBI agents sifted through dirt with rakes and shovels Saturday in the backyard of a suspected serial killer’s home and ran a thermal-imaging device across the ground near the area where the decomposing bodies of several women were found.

The agents worked for about four hours at the home of Anthony Sowell, crawling beneath the front porch and removing bricks and other debris. One agent had a tape measure, while another snapped pictures and a third marked locations with orange paint. They finished up around 1:30 p.m.
