In Ohio, a man answering the door Monday at McVey's home address said he had no comment.
Randy Fisher, president of the Coshocton County Amateur Radio Association, said McVey was a ham radio enthusiast who had come several times to the group's monthly meetings over the last year or two. Fisher said he was shocked to hear of the arrest and said he last talked with McVey about a week ago via radio and always found him friendly and interesting to talk to.
"I was impressed that he was a public-service-minded type of individual. He really enjoyed using his ham radio for emergency services and that sort of thing," Fisher said.
For two years, McVey has been a member of a volunteer organization in his home area that assists the sheriff's department with traffic control at emergency scenes, said Tim Wise, president of Coshocton County REACT, or Radio Emergency Association Citizen Team.
Wise said he was inclined to believe McVey's arrest resulted from a misunderstanding.
"Everything they found on him, with the exception of a gun, he basically had all that when he was in Coshocton," Wise said Monday. "He just basically liked to monitor police frequencies and listen to what's going on."
That's common for REACT members, though members of the organization are not authorized to have police sirens and lights or break the speed limit on the way to emergencies, Wise said.
McVey had to be warned about his speed while responding to REACT calls, Wise said.
"He's kind of a go-getter, and I know we had to kind of clip his wings a couple times and tell him he needed to watch what he was doing out there and slow down a little bit," Wise said.
McVey had a webcam in his car because he liked to chase severe storms. Wise said he was unaware McVey had a gun, but said with certainty he did not believe McVey would ever want to harm the president.
