Sheriff’s officials said a $100,000 reward will be given to anyone with information leading to the arrest of the arsonist responsible for the attack on Harris Farms last month.

The Associated Press reports the fire at California’s largest beef processor destroyed 14 tractors and several cattle trailers. The loss was estimated to total over $2 million.

The North American Animal Liberation press office received an email from an anonymous animal rights activist who claimed responsibility for the blaze.
