A poacher has been ordered to watch the Disney classic Bambi as part of his sentence for illegally killing hundreds of deer.

David Berry was ordered by a court in Missouri to watch the film at least once a month during his year-long jail sentence in what conservation agents have called one of the largest deer poaching cases in state history.

“The deer were trophy bucks taken illegally, mostly at night, for their heads, leaving the bodies of the deer to waste,” said Don Trotter, the prosecuting attorney in Lawrence county in the state’s south-west.

Berry, his father, two brothers and another man who helped them had their hunting, fishing and trapping privileges revoked temporarily or permanently. The men have paid $51,000 in fines and court costs but the judge ordered a special addition to Berry’s sentence for illegally taking wildlife.

Court records show he was ordered by county judge Robert George to “view the Walt Disney movie Bambi, with the first viewing being on or before 23 December 2018, and at least one such viewing each month thereafter” while at the county jail.

Berry was also sentenced to 120 days in jail in nearby Barton county for a firearms probation violation.

His father, David Berry Sr, and his brother, Kyle Berry, were arrested in August after a nearly nine-month investigation that also involved cases in Kansas, Nebraska and Canada. The Missouri department of conservation said information from the investigation led to 14 Missouri residents facing more than 230 charges in 11 counties.

Investigators say Berry Sr’s other son, Eric Berry, was later caught with another person spotlighting deer, where poachers use light at night to make deer pause and easier to hunt.

The investigation into the Berrys began in late 2015, when the conservation agency received an anonymous tip about deer poaching in Lawrence county.
