MARIETTA — A Marietta registered sex offender who threw cinder blocks at motorists and jumped on their vehicles last May was sentenced to 21 months in prison Tuesday.

Robert Jonathan Huffman, 36, of 797 Channel Lane, was sentenced to nine months in prison for one count of abduction, a third-degree felony, and an additional 12 months for violating his parole.

He was given 308 days of credit for time already served in the Washington County Jail and so will be released mid-February next year barring any additional violations while in prison.

“You have a history of violence and several previous offenses,” said Washington County Common Pleas Judge Mark Kerenyi on Tuesday. “So I’m going to impose that your two sentences run consecutively.”

Huffman was only out of prison for 26 days after serving time for a 2014 sex crime conviction when the incident on the roadway took place.

One of Huffman’s victims said she would have liked to see a longer sentence.

“The scary part is next year, nobody is safe,” said one of Huffman’s victims, Amy Taylor, 38, of Marietta, following the hearing Tuesday. “They can make him take his medications when he’s behind bars, but with his history he shouldn’t have had the option to plead down the charges. He’s going to end up hurting somebody and they’re just letting him. It’s going to take him killing someone before they open their eyes.”

Assistant Prosecutor Kelly Hamilton said Huffman had previously spent time in the Appalachian Behavioral Healthcare Hospital in Athens, a facility which provides inpatient care for acutely mentally ill adults from southeastern Ohio. Hamilton said Huffman had been released and deemed sane.

Huffman was originally charged with three third-degree felony counts of abduction but pleaded guilty to only one count on Jan. 7. The maximum sentence the court could have imposed originally was nine years in prison. After the plea agreement, the maximum possible became three years.

Taylor, who at the time of the crime was pregnant, had been headed home from a doctor’s appointment with her husband on the morning of May 17 when the pair came upon Huffman throwing cinder blocks in the roadway on the hill of Channel Lane. By that point he had trapped the vehicle of Teresa Isner, 39, of Marietta.

“We pulled up and saw that he had blocked the road with cinder blocks and there was a white vehicle in the middle of the road with a woman locked inside, terrified,” explained Taylor. “She was screaming, ‘help me, he’s attacking me.’ I called the police and then he ripped the door off the shed and threw it down the hill and ran to our car and started jumping on our hood.”

Taylor attributes the presence of her husband, Jay, to Huffman backing off their vehicle.

“(Huffman) first came to my door and tried to rip it open and when he couldn’t he ran to my husband’s door, but when he saw my husband he slowly backed off and ran back to the other woman’s car and started jumping on it again,” she said.

Isner later told Marietta police officers that she was so terrified of Huffman that she was afraid to move when he blocked her vehicle and his actions caused an anxiety attack. The Taylors also told officials that Huffman had crawled beneath Isner’s car and attempted to tear at the undercarriage before police arrived.

“Then when the police cruisers arrived he took this sumo stance, which was somewhat comical because he was so skinny and wearing shorts and bare feet, and had to be (hit with a stun gun) by the officers,” Taylor said.

Huffman will also be under a mandatory three years of post-release control after serving his sentence. He declined to make a statement at his sentencing hearing Tuesday.

Huffman was in prison for 15 months prior to his April 2016 release for pandering sexually oriented material involving a minor, of which he was convicted in January 2015. In the years prior to that conviction, as far back as 2008, he was also found guilty of the following offenses: menacing, criminal trespassing, corruption of a minor, resisting arrest or failure to comply and assault. The corruption of a minor conviction allotted a 23-month prison sentence to Huffman from January 2012 to November 2013.
