Steven Avery's garage

Searches of Steven Avery's detached garage recovered .22-caliber shell casings and, during a later search, two bullet fragments. Mark Wiegert testified that Teresa Halbach's DNA was identified on one fragment. Brendan Dassey testified that he helped clean a red spill on the garage floor but did not identify it as blood; Avery's defense disputed the shooting account, emphasizing the absence of Halbach's blood in the garage.
