HONOLULU -- A man accused of killing a pet pig may blame the pig as part of his defense.

Joseph Calarudda is charged with stabbing 300-pound "Porky" to death as its owners pleaded for him to stop.

Calarudda is going on trial this week for felony theft of livestock. One of his defenses may be that the pig was aggressive and dangerous.

Prosecutors said they hope to use video of Porky in a television commercial to show how peaceful he was around people. Porky also appeared in the ABC television series "Lost."

The trial could begin on Wednesday.
