As former New England tight end Aaron Hernandez sits in a private cell for his protection, a portrait is emerging of a man whose life away from the field included brushes with violence that started as long ago as his freshman year at Florida.

Details of a series of altercations and gun incidents linked to the Pro Bowler have surfaced since Hernandez was arrested June 26 in the death of a semipro football player who was dating the sister of his fiancee.

Tim Tebow, now a member of the Patriots and at the time Florida's quarterback, was listed as a witness in a sworn court complaint from the Eighth Judicial Circuit. It details Hernandez's apparent involvement in a fight at a Gainesville restaurant in April 2007. It wasn't clear how the case was settled.

Hernandez, 23, has pleaded not guilty in the shooting death of 27-year-old Odin Lloyd, whose body was found June 17 a mile from the defendant's home in North Attleborough, Mass.

Meanwhile, police in Hernandez's hometown of Bristol, Conn., said Tuesday that Boston police have asked for their help with a double homicide investigation linked to the former NFL star. Witnesses reported seeing gunfire coming from an SUV that was aimed at a vehicle carrying the victims, Daniel Jorge Correia de Abreu, and Safiro Teixeira Furtado.
