Sheriff's spokeswoman Andrea Carlson says 46-year-old Leland Kinkey of Eagle Point was running around his property Thursday night naked, screaming and splattered with blood.
Kinkey allegedly told deputies he slammed a lamb into a vehicle and then broke its neck because he was "trying to be a man."
Witnesses told police that Kinkey had earlier tried to rape his wife in front of their two children after getting angry with a vehicle. Carlson says two other adults who live on the property stopped the attack and called 911.
Kinkey has been charged with assault, kidnapping, strangulation, attempted rape and aggravated animal abuse. Bail was set at more than $1 million.
