Stephen Trevor Chapman, 22, was arrested on suspicion of disorderly conduct by deputies from the Pinal County Sheriff's Office on Oct. 19.

A 68-year-old man who found Chapman in bed with his 63-year-old wife in the couple's Saddlebrooke guest house shot at Chapman because he feared for his safety after "Chapman came towards him in a threatening manner."

A 68-year-old man who feared for his safety shot at a 22-year-old man he found in bed with his wife at the couple's Saddlebrooke home early Saturday morning.

The husband called 911 around 1 a.m. to report a shooting at his home in the 38000 block of South Apache Peak Drive in Saddlebrooke, Tim Gaffney, a Pinal County Sheriff's Office spokesman said in a news release.

The husband told deputies he fell asleep in the main house and when he woke up his wife was not in bed, so he went to check their guest house where he found the woman in bed with Stephen Trevor Chapman, the release said. 

The man used his cane to poke Chapman to wake up him and tell him to leave. 

Chapman began to yell profanities at the man and refused to leave, the release said. 

The man then said he was going to call the sheriff's department to ask for help and as he went to get his phone and gun for protection, "Chapman came charging towards him in a threatening manner," the release said. 

The man fired a "warning shot" at Chapman and the round struck a wall and injured Chapman's hand. 

Chapman refused medical treatment and was booked into the Pinal County jail one suspicion of one count of disorderly conduct. 

"This was an unusual call for our deputies in an active senior community," Sheriff Paul Babeu said in the release. "Clearly, this young man should have heeded the warnings of the home owner to leave his residence and to stop sleeping with his wife. The young man is lucky that he only got poked with a cane and hit with a stray pellet from the shotgun."
