Several law enforcement sources told the Courant that Thaddeus Singleton III, 33, was associated with Hernandez and of interest to investigators. Singleton died when his car flew off the road and split a pole in half. Authorities said the car was registered to Hernandez's uncle, who is also Singleton's father-in-law.
Singleton's death was ruled an accident. The Courant reports it was unclear if Singleton knew investigators were interested in his connections with Hernandez, who is facing first-degree murder charges in the shooting death of Odin Lloyd.
Two other suspects in the case -- 41-year-old Ernest Wallace and 27-year-old Carlos Ortiz -- have been taken into custody and extradited to Massachusetts.
Additionally, Hernandez is being sued for allegedly shooting a man in the face, and he's being investigated for a 2012 double slaying in Boston. In 2007, Hernandez, then a student at Florida, avoided arrest after allegedly rupturing a man's ear drum.
