According to police, a couple returned home from a trip Saturday evening to find a large cardboard box with their name and address on it near their front door.

Inside was the cow's head. 

According to the Tribune-Democrat of Johnstown, the couple tried to figure out if they had upset anyone.

Ebensburg police Chief Terry Wyland told the Tribune-Democrat of Johnstown it "caused the victims, especially the wife, stress."

Police say the pranksters came to police headquarters to confess Tuesday night. One of them has experience butchering cows.

The chief isn't naming the suspects. He plans to file harassment and disorderly conduct citations against them later this week.

The suspects, say police, apologized to the authorities as well as the victims, according to the paper.
