PIEDMONT, Okla. -- Oklahoma authorities say a 3-year-old boy who went missing when a tornado struck his home earlier this week is the state's tenth storm-related fatality.

Oklahoma Highway Patrol Capt. Chris West says Ryan Hamil's body was found Thursday morning along the shore in Lake Falcon, near the boy's home in Piedmont. He says Ryan's body was likely washed ashore by changing currents.

The boy's 15-month-old brother, Cole, was also killed in the storm and his mother and sister are hospitalized with injuries.

The children's grandmother, Debra Hamil, says the boys' mother and sister are doing well and are expected to recover.

The storms that spawned the deadly tornadoes killed at least 16 people in Oklahoma, Kansas and Arkansas on Tuesday and Wednesday.
