For a second week, members of the Connecticut State Police dive team today are searching a Bristol, Conn. lake for the gun used in the execution-style murder of a Dorchester man that former New England Patriots tight end Aaron Hernandez is charged with committing, according to a law enforcement official with knowledge of the investigation.

Last week, investigators spent five days scouring the algae-ridden Pine Lake, which sits next to a busy road in Hernandez’s hometown. The weeklong search came up empty, the Globe reported.

Law enforcement officials said the search grew out of a tip that evidence in the slaying of Odin L. Lloyd, 27, who Hernandez is charged with killing, could be found at the lake. The .45 caliber pistol authorities believe was used to kill Lloyd has not yet been found.


Hernandez has pleaded not guilty to all charges and is currently being held without bail.

Hernandez is a Bristol, Conn., native and still has relatives living in the community, including his mother and an uncle whose home is on Lake Avenue, not far from the lake that is being searched.

In June, authorities searched the uncle’s house and impounded a sport utility vehicle found in the garage that Boston police suspect may have been used in a 2012 double homicide.

Hernandez is accused of orchestrating the murder of Lloyd, a Dorchester man who was shot to death in a North Attleborough industrial park June 17.
