A man is facing charges after allegedly breaking into a St. Charles County home while naked.

Joseph Michael Mahoney, 24, of Lake St. Louis is charged with sexual misconduct, property damage and burglary.

Authorities say a man who lives at a home near St. Peters was awakened about 4:30 a.m. Wednesday by someone beating on his bedroom door.

The man picked up a shotgun and opened the door, confronting a naked intruder. The man kept the suspect at bay until St. Charles County deputies arrived.

Lt. Craig McGuire says the deputies found the suspect sitting on the floor, mumbling incoherently and with an odor of alcohol on his breath.
