Robert J. Valentine, the uncle of Aaron Hernandez, was under the influence of alcohol and cocaine when he crashed his moped. The toxicology report indicates negligence led to Valentine's fatal accident, according to the Associated Press.
"An investigation concluded that Robert J. Valentine, who had alcohol and cocaine in his system, drove his scooter in a negligent manner and was solely responsible for his Aug. 3 death in Bristol, police said," the Associated Press wrote on Friday. "Valentine also was operating the scooter at night with dark-colored sunglasses, which likely hampered his vision, they said.
"Valentine, after failing to negotiate a curve in a road, hit a curb, lost control and was thrown from the scooter, suffering a head injury, police said."
Police initially did not suspect foul play, and the toxicology report helped investigators conclude negligence led to Valentine's fatal crash.
Valentine is one of three people with ties to Hernandez to have died since the ex-NFL star's arrest in June. Thaddeus Singleton III, a friend married to Hernandez's cousin, Tanya, died when his vehicle crashed into a Connecticut country club in late June.
Toxicology results revealed cocaine and oxycodone to be in Singleton's system at the time of the crash; he also tested positive for PCP, according to the Associated Press.
Tabitha Perry, Singleton's girlfriend who survived the crash, died in December. Police found her unconscious and not breathing inside her Connecticut home. Although police do not suspect foul play, the investigation is ongoing and awaiting the results of the toxicology tests.
Investigators had planned to speak with Singleton in connection with Hernandez's alleged murder of Odin Lloyd, according to the Hartford Courant; Perry was questioned by investigators in connection to the homicide case but never charged.
Hernandez is charged with first-degree murder in the June 17 shooting death of Lloyd, a friend Hernandez reportedly met through Singleton. Hernandez, 24, pleaded not guilty and is being held without bail while awaiting trial.
He faces life in prison if convicted.
