A 1-year-old boy was fatally shot on Tuesday by his 5-year-old sibling in an Indiana apartment, according to police.
Lafayette Police responded to the apartment after a reported shooting. When they arrived they found the 1-year-old boy dead from a gunshot wound, police said.
The Tippecanoe County Coroner identified the 1-year-old as Isaiah Johnson, according to the Journal & Courier.
The coroner’s autopsy confirmed the young boy died from one gunshot wound but the manner of death is still pending, Journal & Courier reported.
