Three western Iowa teens are charged with brutally beating another teen last weekend. The Cass County Sheriff’s Office says the victim was a 19-year-old Cumberland man. The suspects are: 19-year old Alexander Dvorak, charged with attempted murder, 19-year-old Cody Hogatt and 18-year-old Jonathan Pilgreen — all of Griswold.

A warrant was issued for Dvorak, who’s a U.S. Marine. He’s under arrest in California and is awaiting extradition to Iowa. Cass County Attorney Dan Feistner says the Marine Corps has been helpful in dealing with the suspect. Hoggatt and Pilgreen are being held in the Cass County Jail on $10,000 bond, charged with conspiracy and willful injury.

According to court documents, Dvorak was involved in a planned assault on the victim, whose name was not released. He allegedly went to Cumberland early in the morning on July 4th, with others, to assault the 19-year-old.

Dvorak allegedly punched the victim, jumped on top of him and repeatedly beat him while he was unconscious. The victim was treated at an Omaha hospital for multiple fractures and complications with breathing.
