LOUISVILLE, Ky. —An IAN Alert was issued in Kentucky on Tuesday for a missing 5-year-old boy, and now troopers say he has been found dead.

The boy, Silas, walked away from his home in Cub Run, Kentucky around 8 a.m., according to Kentucky State Police. Cub Run is in Hart County, near Mammoth Cave.

Because Silas has autism, the specific IAN Alert was issued around 9:30 a.m.

Around 10:15 a.m., KSP said he had been found dead.

“KSP grieves with this family and the community,” troopers said in a release.

Tuesday actually marks the one year anniversary of IAN Alert system’s start date in Kentucky. It uses the same system as the Amber Alert.

It was named for Ian Sousis, a 9-year-old boy with autism who ran away from the Children’s Home of Northern Kentucky and drowned in the Ohio River in 2022.
