ST. JOHN'S, N.L. -- Nelson Hart has been found guilty of making threats during a clash with jail guards two years ago in St. John's, N.L.

Hart, now 46, was in Her Majesty's Penitentiary on June 24, 2013, pending an appeal of a murder conviction in the deaths of his three-year-old twin daughters.

A jail guard who spilled Hart's lunch in a dispute that ended with Hart being hauled to segregation with his pants around his ankles denied in court he was targeted.

Hart was tried before a judge alone on three counts of making threats and one count of mischief to property.

He was found guilty on all three counts of making threats by Judge Mike Madden and a guilty verdict was recorded on the mischief charge as the defence presented no evidence on that count.

Madden sentenced Hart to a 60-day conditional sentence to be served in the community and one year of probation.

In a video shown in court, Hart swings a hot kettle into a television after a guard spilled his meal, then gathered other food that was not allowed in his cell.

Hart was freed last August after the Crown said it lacked evidence to retry him for first-degree murder in the 2002 drownings of his daughters at Gander Lake.
