UPDATED, 5:25 p.m. | Kansas City, Missouri, police confirmed that a young boy under 5 years old died in a triple shooting Monday afternoon in Kansas City, Missouri.
Police said that at least one shooting victim showed up at 3211 Indiana Ave., where Kansas City Fire Station No. 18 is located. The shooting, according to police, occurred at East 33rd Street and Agnes Avenue, and the victims drove to the fire station for assistance.
The three victims were shot inside a car, according to police. Two adults, a man and a woman, also were struck by gunfire and were listed in stable condition.
A fourth person was in the vehicle but not injured.

Police spokesman Sgt. Jake Becchina said it appeared the shots were fired at close range while the vehicle was parked outside a home. He said the shooting showed an "absolute complete lack of regard" for anyone in the vehicle, including the child.
Jackson County Prosecutor Jean Peters Baker said she hopes that there will "some measure of justice" for the boy's death.
"Time will get us there. And I pray that someday I can look at a family that's grieving and tell them, in a community that's grieving, and tell them that there is some justice that's going to come their way," Peters Baker said.
Mayor Quinton Lucas, who went to the scene of the shooting on Monday afternoon, said the child's death was a reminder of gun violence in the community.
In late June, 4-year-old LeGend Taliferro was shot and killed while sleeping in his family's apartment.
"At a time … where we’ve had a lot of tragedies, you hate to hear about something like, particularly about the death of a young child," Lucas said.
Both Lucas and Becchina urged anyone in the area who witnessed the shooting or might have information to call the Greater Kansas City Crime Stoppers Tips Hotline at 816-474-8477 (TIPS).
