Police said the shooting occurred at about 1:43 p.m. Monday at a home in the 2000-block of 60th Street. Officers were contacted by staff at Froedtert South Hospital - Kenosha Campus on 8th Avenue.
The man who lives at the home wasn't there at the time of the shooting.
"I wasn't at home," Curtis Cannon said. "It was an accidental shooting. My kids did not intentionally shoot no five year old kid."
Cannon said the boy's name is Cory, and is the son of his daughter's boyfriend. Police said two people drove the boy from the house to a hospital a few blocks away and just dropped him before driving off.
"Maybe they were scared to death. Maybe they took him to the hospital because they realized they f---ed up and didn't want the boy to be in pain or suffering. I don't raise killers. It was an accidental shooting," Cannon said.
Police said the two people who transported the boy to the hospital have been identified, located and interviewed as of Monday night. Police also said the firearm believed to be involved in the shooting has been recovered.
"There's nothing bad to say about this family. It was a tragedy that happened right here," said neighbor Robert Coronado.
Police said the investigation is ongoing and more information will be released at a later time.
