Chicago police say a 3-year-old boy has died after being accidentally shot in the head by his 6-year-old brother.

Authorities said the boy was carried by a relative to a hospital after being shot about 9:05 p.m. Saturday, and was later pronounced dead at a different hospital. Police say the father knowingly stored the loaded revolver on top of a refrigerator where children could access it. He has been charged with felony child endangerment.

Police said the father would appear in bond court Sunday.
