The man married to the cousin of Aaron Hernandez, who died it a high-speed crash in Farmington in June, had drugs and alcohol in his system, according to police.
Toxicity tests done on 33-year-old Thaddeus Singleton III found cocaine, Oxycodone and alcohol in system at the time of his death, police said.
Singleton was the driver of a car that slammed into the Farmington Country Club on June 30. He died in the crash.
Singleton was married to Hernandez's cousin and lived with Hernandez's uncle, Andres Valderamma, in Bristol, according to authorities.
A woman who was in the car with Singleton, Tabitha Perry, survived the crash, but died earlier this month. Police found Perry unresponsive after receiving a 911 medical call at 25 Darling Street around 3 a.m. on Dec. 16. She was pronounced dead at the hospital shortly after. Police found no suspicious circumstances and detectives are waiting on a toxicology report to determine how she died.
Hernandez, a Bristol native and former New England Patriot, has been indicted in the murder of Odin Lloyd, a 27-year-old Massachusetts man who was dating the sister of Hernandez's girlfriend.
Hernandez has pleaded not guilty.
