A 23-month-old Topeka boy died Monday after being left in a parked car during the afternoon.

The boy’s sister found him in a car near 22nd and Jefferson streets in south Topeka and called the police immediately. The boy was transported to a Topeka hospital but died later Monday.

Neighbors said the grandmother – who had just returned from running errands – typically watches the child. It wasn’t known how long the child had been in the car.

No arrests have been made, and the incident is still under investigation.
