MERIDEN, Conn. — A police officer who fatally shot a man who was beating his father with a baseball bat in Meriden on Sunday had to fire nearly 20 rounds at the man before the son finally fell backwards, stopping the attack. Body camera footage from the police officer who fired the shots, identified as Officer Anthony Offiaeli of the Meriden Police Department, showed the brutality of the bat attack and the moments that preceded the shooting. The footage was released Tuesday along with a preliminary report from the Office of Inspector General, which is investigating to determine if the shooting was justified under Connecticut law. In his preliminary report, Inspector General Eliot Prescott identified the assailant who was shot multiple times as 38-year-old Robert Lee Jenkins III. Though Prescott did not name the victim in his report, he has been identified as 69-year-old Robert Jenkins , Jr. According to the Office of the Chief Medical Examiner , Jenkins III died from multiple gunshot sounds of the torso. Jenkins, Jr., died of blunt force head injuries. Both deaths were ruled a homicide, a spokesperson for the medical examiner said. According to Prescott, officers responded to a home on Sagamore Road around 10 a.m. in connection with an active domestic violence incident. Offiaeli’s body camera footage shows him arrive first to the scene, at which point he suddenly shifts his cruiser into park, rushes out from the vehicle and radios in for backup to “step it up.” Offiaeli immediately begins shouting for Jenkins III to drop the bat as he can be seen on the front lawn viciously striking his father, the footage shows. “Put the (expletive) bat down, put the (expletive) bat down,” Offiaeli shouts with his gun drawn. “Put it down.” As he approaches, Offiaeli’s body camera captures Jenkins III repeated
