Investigators have determined that a man who exchanged gunfire with Fall River police during a July standoff died of a self-inflicted gunshot wound, the Bristol County District Attorney’s Office announced Wednesday.

Police were called to a Langley Street home around 1:30 a.m. on July 15 after family members expressed concern that 38-year-old Domonick Knight was potentially armed and in crisis.

Once nearby residents were evacuated, a crisis negotiator responded, but police said attempts to make contact with Knight for nearly two hours were unsuccessful. Officers forced their way into the home around 3:15 a.m.

“Investigation into this matter has determined that the decedent, who was in possession of firearms, was the first to fire a weapon,” the DA’s office wrote. “The decedent fired his weapon at police shortly after their entry into the residence.”
