(WAYNE) - A man who opened fire outside a Wayne, Michigan church on Sunday was struck by a vehicle and then fatally shot by security staff.

During a Sunday evening news conference, Wayne Police Chief Ryan Strong says Churchgoers attending a morning service at CrossPointe Community Church in Wayne spotted the gunman driving recklessly. They next saw him exit his car wearing a tactical vest and carrying a rifle and a handgun.

The man began firing as he approached the church, striking one person in the leg. Strong says a parishioner struck the gunman with his vehicle as the gunman shot the auto repeatedly, and at least two staff members shot the gunman, causing the fatal wounds.

The suspect is described as a 31 year old white male with no known connection to the church. His motive remains unclear, but it appears he was suffering from a mental health crisis, according to Strong.

The shooting occurred around 11 AM. The person who was shot in the leg was treated for non-life-threatening injuries. Nobody else was hurt.

About 150 people were inside the church at the time. The church's website says it hosts a worship service on Sundays at 10:45 AM.
