Garrett went to Newhouse's home, which is across the street from the shop, and knocked on the front door. Newhouse greeted him at the door, machete in hand, according to the complaint.
Garrett and other witnesses told deputies Newhouse swung the machete and threatened to cut him.
A charge of misdemeanor assault was dismissed when Magistrate Traci Carper-Strickland found Newhouse not guilty.
He was arrested three months before the machete incident for shooting a woman he tried to have sex with. Newhouse was charged with malicious wounding in December 2008 after shooting Dawn Withrow, 35, of Elkview, according to Daily Mail archives.
The shooting occurred at the Sissonville Drive home of Sheryl Summers, Withrow's friend.
She said Withrow was resting on a bed and she was sitting in a chair nearby when Newhouse began removing his clothes. He also tried to remove Withrow's clothes, and continued even after she told him no. He told her he wanted to have sex with her.
Summers then pulled a .22-caliber handgun from her purse and pointed it at Newhouse to stop him. Newhouse and Summers struggled for the gun but he gained control of it and turned it on her.
Summers then pulled a fishing knife to defend herself. Newhouse fired one shot into the ceiling. Withrow was standing between Newhouse and Summers when he fired the second shot, striking Withrow in the upper right chest. She survived her injuries.
The status of that case was not immediately available Wednesday.
Newhouse was charged with one count of first-degree murder in Wednesday morning's shooting. He is being held at South Central Regional Jail without bond.
