BEND, OR -- A Bend man faces Attempted Rape and other charges, following an incident at a home south of Sunriver, Sunday evening. According to the Deschutes County Sheriff's Office, 47-year-old David Sigel was drinking with 43-year-old Matthew Coats and a 40-year-old woman at Coats' home on Lazy River Drive. Investigators believe Coats passed out and Sigel attempted to rape the woman. She yelled for help and Coats awoke. The men got into a physical altercation and Sigel left the house on foot.

Coats then allegedly drove to Sigel's home on Whittier Drive, firing half a dozen shots into the air from a .40 caliber handgun. Deputies say he then entered the home and fired three more shots into a wall and ceiling. Several witnesses called 911 to report the gunfire, just before 7 p.m., Sunday. Coats was later contacted back at his Lazy River Drive house by Deputies.

A search warrant was executed at Coats' home, where investigators found a gun that matched the one fired inside Sigel's home and evidence related to the attempted rape. 

Sigel is charged with Sexual Abuse I, Coercion, Strangulation and Assault IV, on top of the Attempted Rape. Coats faces Burglary I, DUII, Menacing and other charges.
