Aaron Hernandez Murder Investigation Continues as Police Search Conn. Lake for Murder Weapon

On Monday authorities from Connecticut and Massachusetts searched a lake in the hometown of Aaron Hernandez, the former New England Patriots player who is charged with murder.

Connecticut police did not reveal the reason for the search at Pine Lake in Bristol and referred further inquiries to Massachusetts prosecutors. Police divers were in Pine Lake and other officers could be seen wading in the water and also searching along the lake's edges.

Hernandez has pleaded not guilty to murder in the death of Odin Lloyd, a 27-year-old Boston semi-professional football player whose body was found June 17 about a mile from Hernandez's home in North Attleborough, Mass. Hernandez's attorneys have called the case against him circumstantial.

Authorities believe Lloyd was killed with a .45-caliber Glock, which hasn't been recovered.

Hernandez was charged with murder and carrying a firearm without a license in relation to the death of 27 year old Lloyd.

The victim in the incident was found dead in a field less than half a mile away from where Hernandez resides.

Authorities now believe they have enough evidence to show that Hernandez shot Lloyd twice. He then allegedly stood over Lloyd's body and shot him a further three times.

Investigators have recovered .45 caliber shell casings from the scene of the killing, although at the moment they have not been able to locate the murder weapon.

Prosecutors believe that on June 17 Hernandez and two other men picked up Lloyd in Dorchester at about 2.30 a.m. in their rented Nissan Altima.

They described that Hernandez was allegedly upset with Lloyd for speaking to someone at Club Rumor in Boston earlier in the weekend. He allegedly said that he could not trust Lloyd, according to investigators.
