SIOUX CENTER, Iowa (KAKE) — Authorities say a 20-month-old boy died Saturday in an accident on his family's farm in Iowa.

The incident happened just before 6 p.m. about four miles west of Sioux Center. The Sioux County Sheriff’s Office said the boy's father was driving a GMC Yukon on the property when he stopped to unhook a trailer. He struck Walker Maassen while driving away. 

Walker was taken to a local hospital where he passed away. 

A release from the sheriff's office did not provide additional information about the tragedy. 

"Walker was deeply loved by his family, especially his older siblings. His big brown eyes and smile would light up any room he entered," Walker's obituary says.
