TAMPA —A man once declared criminally insane after killing a stranger was sentenced to 18 months of house arrest Monday for illegally possessing firearms.

David Harris Dunaway, 58, of Hawthorne, was acquitted by reason of insanity in 1993 after fatally shooting a truck driver Leonard Brower at a Wildwood gas station.

Last December, he was arrested en route to a flea market in a van with three dozen guns, illegal under federal law for someone with his medical history.

The house arrest is one requirement of a three-year term of supervised release imposed by U.S. District Judge James D. Whittemore, along with 300 hours of community service.

Dunaway is a lifelong outdoors man. The judge banned him from possessing guns but noted in his order that Dunaway is not prohibited from bow-hunting.
