Fred was killed on May 3, 2007, by an eleven year-old boy.

The location was the Lost Creek Plantation (”commercial hunting
preserve” (i.e., “canned-hunt”)) outside Anniston in northeast
Alabama. The pig [Fred] was claimed to weigh 1,051 lb. (477 kg.) and
with a
length of 9 ft. 4 in. (2.84 m) from the tip of its snout to the end of
its tail. The pistol used was a fifty (.500) calibre high-powered
pistol.

A newspaper account has area killed it at 150 acres. A square half-mile
is 160 acres.

Additionally from Wikipedia:

Several days after the story broke, suspicion mounted over the
authenticity of the photographic evidence. Analysis by a retired
physicist from New York University revealed that, were the photo
genuine, the pig would in fact be 15 ft long, not the mere 9 ft
claimed.

As a result of the suspicions, the NBC Today Show cancelled a planned
segment on the pig, on May 29.
