He has also pleaded not guilty to a witness intimidation charge for allegedly shooting Alexander Bradley, his former friend and marijuana supplier, in Florida in February 2013 in an effort to silence him over the killings.
Bradley has loomed large over deliberations. On Monday, jurors asked Suffolk Superior Court Judge Jeffrey Locke about the intimidation charge.
Locke said the question was “insightful” and that he would consider the matter overnight before providing an answer Tuesday morning.
The question Monday followed an earlier inquiry from jurors on Friday.
They asked Friday, “If an immunized witness provides specific testimony that we believe would give enough evidence for a conviction, do we have to have corroborating evidence for that specific piece of testimony?”
Locke told jurors that a defendant cannot be convicted solely on the word of an immunized witness, and that additional evidence must corroborate at least one element of the charged offense.
Among the immunized witnesses who testified at trial was Bradley.
He told jurors he was driving Hernandez’s Toyota 4Runner when the athlete reached across him and fatally shot de Abreu and Furtado as they sat in a BMW at a stop light.
Bradley also said Hernandez shot him in the face inside a vehicle in Riviera Beach, Fla. and left him for dead in a parking lot.
The defense claims Bradley, an admitted drug dealer currently jailed in Connecticut for shooting up a Hartford club in 2014, shot de Abreu and Furtado over a drug deal, and that someone else shot Bradley over another botched drug sale.
Hernandez is already serving a life sentence for the June 2013 fatal shooting of Odin L. Lloyd, a 27-year-old Dorchester man who was dating the sister of Hernandez’s fiancee at the time of his death.
The state’s highest court will automatically review Hernandez’s first-degree murder conviction in the Lloyd case at a later date.
