The Marlin Glenfield model 60 semi-automatic .22 caliber rifle that Steven had hanging above his bed is the alleged murder weapon. A .22 caliber bullet with the victim's DNA on it was determined to have been fired by this rifle.

Steven claimed he never used this rifle, however two people have said they have seen him use it. In his bedroom a pack of CCI lead bullets were found which can be used for this rifle.


On Sunday 6 November 2005,[1] one day after the discovery of the Toyota RAV4, CASO deputy Daniël Kucharski was assigned by Lieutenant Bowe to search Steven Avery’s trailer to specifically collect any weapons, a vacuum cleaner and bedding from the spare bedroom in the trailer.

Throughout the day Kucharski was assisted by three manpower resources from MTSO: Lenk, Remiker and Colborn.[1]

The men entered the trailer a 12:25 and collected two guns that were in a gun rack in Steven Avery’s bedroom in the back of the trailer. One was a Marlin Glenfield model 60 semi-automatic .22 caliber rifle. The other was a .50 caliber muzzleloader.[1]
