A man staying at a homeless shelter has wounded four people in a chainsaw and knife attack.

The Callaway County sheriff's office says 28-year-old Matthew Watkins is facing four counts each of first-degree assault and armed criminal action for the attack at the Mid-America Care Center. The homeless shelter is connected with Christian television station KNLJ.

Sheriff Dennis Crane says two victims were cut by a chainsaw and two others by a knife. Three of the victims were taken to hospitals, and Crane says at least one of those is in serious condition.

The sheriff's office says Watkins is originally from St. Louis. He is being held on $600,000 bond.
