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 that 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.

Lloyd was shot six times.

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

The murder weapon has never been found.
