Pasco Police are still investigating the discovery of a dead teen, whose body was spotted on the Pasco end of the railroad bridge Saturday evening.

Around 6:30PM police were called by railroad workers who spotted the body. Police say is a teen male, wearing a skull mask very similar to the one pictured. Preliminary investigative works shows he was likely hit by a train and killed.
