The fathers of two men gunned down in Boston in 2012 described the devastating toll of their loss Thursday, as their lawyer insisted that “an abundance of evidence” points to former New England Patriot Aaron Hernandez as the shooter.

Speaking during an evening press conference at their lawyer’s office here, the fathers of Daniel Abreu and Safiro Furtado held pictures of their sons and grew emotional as they spoke to reporters.

“We want to let people know that his death is killing us inside,” Furtado’s father, Salvador Furtado, 57, said through an interpreter.

Abreu’s father, Ernesto Abreu, said softly, “He was a good boy,” and broke down crying when asked to recount the difficulty of losing his son.

Both families filed wrongful death lawsuits this week against Hernandez, 24, in Suffolk Superior Court, seeking $6 million each from the jailed athlete who has been charged in another killing. Hernandez’s lawyers had no comment on the suits.

The families contend in court papers that Hernandez “wilfully, recklessly and/or maliciously shot a firearm from inside of his motor vehicle” in Boston’s South End on July 16, 2012, striking the two men as they sat in another car.

“The fatal attack was without provocation or justification,” the documents state.

Hernandez is being held without bail at the Bristol County House of Correction and Jail in North Dartmouth on separate murder and weapons charges in the execution-style slaying of Odin L. Lloyd, 27, of Dorchester in June 2013. He has pleaded not guilty.

Lloyd’s body was found at an industrial park near Hernandez’s sprawling North Attleborough home. Law enforcement officials have told the Globe that investigators believe that Hernandez was worried about what Lloyd might know of the killings of Furtado and Abreu.

On Thursday, the lawyer for the families of Furtado and Abreu, William T. Kennedy, said his clients are basing their assertion that Hernandez shot the two men in part on court records that have surfaced in related investigations.
