COLUMBUS, Ohio — A U.S. attorney said Tuesday that Justice Department and FBI investigators will help review the fatal shooting by an Ohio sheriff’s deputy of Black man whose family says that he was holding a sandwich, not a gun, and that he was shot in front of his grandmother and two toddlers while inside his home, not outside it.

After the state attorney general’s office said it wouldn’t be able to investigate because Columbus police took too long to bring the case to their attention, the office of U.S. Attorney David M. DeVillers in Ohio said Tuesday that it would look into the matter along with the Justice Department’s Civil Rights Division, the FBI in Ohio and the local police.

The Franklin County Sheriff’s Office first reported Friday the fatal shooting of a man that day on the north side of Columbus. It wasn’t until Sunday, more than 48 hours later, that police revealed details such as the name of the victim, Casey Goodson Jr., and the deputy who was involved.

Since then, Goodson’s family members and law enforcement officials have given conflicting details.
