FOND DU LAC, Wis. -

A Campbellsport man has been convicted of tying a teenager upside-down and ordering his dog to attack because the man thought the teen was burglarizing his home.

A Reporter of Fond du Lac report said 59-year-old Richard Lisko was convicted Friday of first-degree reckless injury and false imprisonment.

Prosecutors said Lisko hung 18-year-old Joel Kennedy upside-down by his ankles for more than an hour and periodically ordered his dog to attack. Kennedy suffered cuts and punctures to his neck, ears and scalp.

Defense attorney Dan Stevens told jurors that police made a "snap judgment" to believe the teen's story, and investigated accordingly. He said the teen lied to police to hide his burglary attempt.

Prosecutor Dennis Krueger said the teen's feet were numb for almost a month after the attack.
