(AP) — A Wichita toddler who fell into a backyard fish pond earlier this week has died.

A spokeswoman for Wesley Medical Center said that 17-month-old Ethan Joshua Kimmi died Thursday morning.

The boy was pulled from a koi pond at his grandparents’ home around 7:30 a.m. Monday and taken to the hospital in critical condition.

Police have said Ethan was playing in a screened-in area of the home and apparently got out through a dog door. The death has been ruled an accident.
