LAKE WORTH, Fla. —  Two men will spend a year behind bars for killing a goose in South Florida while a 17-year-old will serve his time under house arrest.

Twenty-year-old Christopher Mullan, 18-year-old Anthony Karney and a 17-year-old were sentenced Friday. They pleaded guilty to felony cruelty to animals and will also serve three years' probation.

The judge required that they earn high school diplomas during their time, perform community service working with animals and undergo psychiatric evaluations.

The goose, Lily, was killed in December. Authorities say the three defendants chased the goose around a Lake Worth yard and took turns swinging an aluminum bat at her.

A tip led to their arrests in March. The three apologized in court.
