Authorities say the tractor operator used the tractor’s 4-foot-long forks to impale a cow.

According to The Associated Press, Pennsylvania State Police Trooper Stephen Limani said investigators believe the act was deliberate, involving more than one person.

Police say the cow is valued at about $1,000.

"Most likely, our criminal is going to be somebody who is familiar with these types of tractors," Limani told WPXI. "It's pretty alarming and sad that we would have someone who would commit a crime like this."
