Several shell casings were found in Steven Avery’s garage on various days. The shell casings were forensically matched to the rifle Avery had in his bedroom.

Steven Avery claims no rifle was ever fired inside his garage. He says the shell casings got in his garage because his nephews would fire his rifles around the yard. Avery explained he picked up the shell casings and threw them in his garage.

Summary

Discovery

On Saturday 5 November 2005, the same day the Toyota RAV4 was found on the Avery’s Auto Salvage property, investigators started searching the property.

At 14:35 hours Calumet County Lieutenant Kelly Sippel arrived on the Avery property and began searching the outbuildings on the Avery property and started with several garages located in the northwest corner of the property.[2] The first garage Sippel searched was Steven Avery’s garage. Sippel found a Suzuki Samurai vehicle and numerous .22 shell casings on the floor of the garage.[2] According to Dave Remiker of Manitowoc a total of eleven shell casings were found.[3]

On Wednesday 1 March 2006 Brendan Dassey confessed to lead investigators Thomas Fassbender of the DCI and Mark Wiegert of Calumet County Sheriff’s Department that in his presence, Steven Avery shot Teresa with a Marlin Glenfield .22 caliber rifle from his bedroom. Following this confession, investigators from the DCI and CASO, with assistance from MTSO, searched the garage again. Unlike previous times, the garage was now considered part of the crime scene and thoroughly searched for two days.
