WICHITA, Kan. (AP) — A 17-month-old girl has died from injuries that Wichita police suspect are the result of child abuse.

The Wichita Eagle  reports that the girl was pronounced dead around 8:10 a.m. Saturday. Her mother’s boyfriend has been charged with child abuse and aggravated battery.

Wichita police Capt. Jeff Weible says that when emergency crews arrived Monday, they were told the girl had fallen about 30 minutes earlier. The boyfriend had been caring for the girl and her 4- year-old sister while their mother was working.

Weible says the baby had multiple bruises and other internal injuries that are “indicative of child abuse.”
