AMES, Iowa (AP) — A man shot two females to death and then apparently killed himself outside a church in Ames.

The Story County Sheriff’s Office says the man killed the two females outside the Cornerstone Church, a megachurch on the outskirts of Ames. Investigators didn’t know the ages of those killed. FOX 8 sister station WHO reports the church was hosting an event for college-age individuals.

The shooter appeared to have then shot himself but his death is still being investigated. The church is near Interstate 35, about 30 miles north of Des Moines. The sheriff’s office didn’t identify those killed or give details about what led to the shooting.
