A 78-year-old man who was badly beaten while trying to defend a tenant during an armed home invasion in Providence has died of his injuries. The Providence Journal reported Tuesday that Delor Cabral died Sunday at Rhode Island Hospital. Cabral, a former sheriff, was critically injured last month when he tried to defend his tenant from gunmen who broke into the Ontario Street dwelling. Wilbert Richardson and Joel Valdez are being held at the Cranston jail on several charges in connection with Cabral’s beating. Police Commander Thomas Oates III said investigators are waiting for the medical examiner’s office to determine Cabral’s cause of death to see whether it will be ruled a homicide.
