Video shows Aaron Hernandez dancing near gas pump before killing

FALL RIVER, Mass. - Surveillance video shows former New England Patriots player Aaron Hernandez putting gas in his rental car and dancing near a pump about an hour before prosecutors say he killed a man.

Hernandez is charged with killing Odin Lloyd in the early morning hours of June 17, 2013. Lloyd was dating the sister of Hernandez's fiancee.

The video played Thursday in the former NFL star's murder trial shows a co-defendant wearing a white towel around his shoulders.

A white towel was found near Lloyd's body later that day in an industrial park not far from Hernandez's home. Lloyd was shot to death.

Prosecutors haven't said who shot Lloyd but said Hernandez orchestrated the killing.

Also Thursday, a bar manager testified that Hernandez spent the earlier part of the night of June 16, 2013 drinking with a group at a bar in Rhode Island and smoking marijuana outside the bar with one of his friends.

The bar manager, Kelly Rose Belanger, said Hernandez paid the $243 bill and left a $30 tip at around 12:15 a.m. Lloyd was dead around three hours later.

On Wednesday, a state police sergeant testified a shell casing found in a car rented by Hernandez and another found at the scene of the killing were fired from the same weapon.

Five shell casings were found near where Lloyd was shot to death in the industrial park. An employee of a rental car business has previously testified that she found one shell casing under the driver's seat of Hernandez's rented Nissan Altima, which he 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 .45-caliber casings were fired by the same gun. He said they were consistent with having been fired from a Glock.

The murder weapon has never been found.

During cross-examination, the defense went after Walsh for not looking more thoroughly for ways to match the bullets, such as by contacting the manufacturer or by checking a national database for comparing bullets.
