Cop: Shell casings found at murder scene, in Hernandez's rental car were fired by same type of gun

FALL RIVER, Mass. (AP) — A Massachusetts State Police sergeant has testified that the shell casings found in Aaron Hernandez's rental car and at the murder scene were fired from the same weapon.

Five shell casings were found at the scene where Odin Lloyd was killed in June 2013. An employee of a rental car business has testified she found one shell casing in the Nissan Altima that Hernandez rented and returned the day of the killing.

Police later found that shell casing in a trash bin at the business.

Sgt. Stephen Walsh testified Wednesday that his examination determined all six casings were fired by the same gun. He says they're consistent with having been fired from a Glock.

The defense went after Walsh for not looking more thoroughly for ways to match the bullets.

The murder weapon hasn't been found.

Hernandez, a former tight end for the New England Patriots, is on trial for murder. He is accused of having killed Lloyd.
