A three-year-old boy in Cleveland, Ohio shot and killed a one-year-old boy after picking up a handgun that had been left unattended inside a home on Sunday.
The infant was rushed to hospital with a gunshot wound to the head but was later pronounced dead, reports the Associated Press.
Investigators were trying to determine where the gun came from, Cleveland Police Chief Calvin Williams told reporters.
Though full details behind the shooting have not been released, Williams said there was at least one adult home when the incident happened.
"It's a sad day for Cleveland," said Williams. "This fascination that we have with handguns, not just in this city but in this country, has to stop. This is a senseless loss of life."
