UNION, Maine — A local man was arrested Friday on charges he beat another man using exercise equipment and then locked the man in a cabin.

Harlan E. MacKenzie, 39, of Union is charged with elevated aggravated assault, terrorizing, obstructing report of crime or injury, and theft by unauthorized taking. He is being held at the Knox County Jail in Rockland with bail set at $5,000 cash or $100,000 surety.

The victim, a 49-year-old Union man, was taken to Penobscot Bay Medical Center in Rockport early Tuesday morning and was transferred at about 6 a.m. that day to Maine Medical Center in Portland for treatment of cuts, bruises and a possible fractured jaw. The victim has since been discharged from the hospital.

According to court documents, the victim was getting ready to go to bed in his cabin at Mount Pleasant Farm on Monday evening when MacKenzie and Joshua Weston, 27, of Union entered the cabin.

MacKenzie told the victim that he had a big mouth and started punching him, according to the victim’s statement filed with Knox County Superior Court.

The victim’s report details MacKenzie hitting him with his own exercise equipment and choking him. It indicates MacKenzie, who lives in a camper about 100 feet from the man’s cabin, was upset over his landlord prohibiting him from drinking outside the camper and apparently blamed the victim.

According to the victim’s report, Weston warned MacKenzie he was going to kill the victim if he kept choking him.

“Harland [MacKenzie] replied, ‘Yeah, that’s the intention so shut up and mind your own business or you’ll get some,’” the victim wrote.

MacKenzie told the victim during the beating that it was his fault the landlord told MacKenzie he was no longer allowed to drink outside his home, according to the victim’s report.

MacKenzie stopped punching the victim long enough to take his keys, wallet and cell phone away, according to the statement, and when MacKenzie finished hitting the victim, MacKenzie told him, “I should take you for a ride where no one will find you and just finish it.”

“I thought he was going to kill me,” the victim wrote.

The victim wrote that MacKenzie told him he would be back in the morning to figure out what to do and then locked him in the cabin.

A man identifying himself as the victim’s brother called police just before 11:50 p.m. Monday and said a man had been beaten and locked in a cabin. Two sheriff’s deputies were dispatched to the scene.

Knox County Sheriff’s Deputy Douglas Brundrett wrote in his report that he and another deputy arrived and asked the victim to open the door. The man told them he couldn’t and slid a key to the outside door’s padlock to the officers through a window.

The officers entered the cabin and found the victim heavily bruised, according to the police report. The victim had been assaulted and had been locked in the cabin for about an hour and a half.

Deputy Matthew Elwell said that when police spoke with MacKenzie at his camper, he denied knowing of any incident. The police searched his home for the victim’s belongings and found nothing, Elwell indicated in his report.

The landlord, Steven Plummer, told police he was allowing MacKenzie to live on his property in exchange for work on Plummer’s farm. Plummer told police that he had issues with the man in the past.

MacKenzie’s criminal record includes two assault convictions, an OUI, criminal mischief, criminal trespass, two convictions of aggravated criminal mischief and violating condition of release.

There was no indication Friday of whether Joshua Weston would face any charges.

No date had been set Friday for MacKenzie’s court appearance.
