PROVO — The Humane Society of Utah is increasing its reward for information leading to a conviction of a suspect in the torture of several cats around Provo over the past month.

The group is now offering a $5,000 reward, up from the $3,000 reward announced last week.

Provo police say the first incident involved four cats that had been bound with tape, strangled with rope or wire and burned. A few of the animals had been laid on the railroad tracks to be decapitated or cut in half.

Police say two more dead cats recently turned up in the same area.

Investigators think someone is trapping the animals.

At least one of the cats was someone's pet. It's not clear if the others were strays or had homes.
