ESTES PARK, Colo. -- Nine Delta Chi Fraternity pledges were arrested over the weekend in Estes Park, suspected of causing more than $10,000 in damage in two motel rooms.

Employees of the Super 8 Motel called police at about 2:30 a.m. Sunday and found large holes in the walls of the two rooms, damaged furniture, blood and vomit, and urine in a coffee pot.

"You don't believe that college kids would have such disregard for other people's property,” said Tom Giffiths, hotel manager. “I’ve seen a lot of damaged motel rooms, but not like this. They haven’t left us anything in here.”

Police said all of the University of Colorado students were not old enough to drink and were arrested on suspicion of underage drinking, and felony criminal mischief.

"We found a keg of beer with a tap and several bottles of hard liquor," said Detective Rick Life with the Estes Park Police Department.

Delta Chi's Boulder chapter was placed on suspension as a result of the incident. A representative of Delta Chi Fraternity Inc.'s national headquarters in Iowa was flying to Colorado Tuesday to investigate.

Sanctions for the Boulder chapter could range from a warning to a fine to expulsion from Boulder’s Interfraternity Council.

Police confiscated cell phones from those involved after learning that several took cell phone photographs and videos of the damaged rooms.

Among those arrested were Andrew Sapiro, 19; Anthony Cronin, 19; Britt Cherster, 19; Kyle Jungels, 18; Kyle Maltz, 18; Lukas Feyh, 20; Matthew Bowen, 19; Nicholas Mortimer, 18; and William Martin, 19.

The pledges were dropped off at the hotel by other fraternity brothers for a weekend planning retreat, according to police.

Police say hotel workers walked in and immediately smelled the stench of beer, cigarettes and bodily fluids. They found ceiling fans ripped down and torn apart; lamps and pictures ruined; heating units ripped off the wall and torn apart; shower curtains and rods pulled down; phones broken into pieces; vomit and blood on various surfaces; tables in pieces; a shattered mirror; a broken dresser; a coffee pot that had urine in it; and other ruined furniture.

"My understanding is that it wasn't an initiation-type thing, but a planning, getting-to-know-each-other thing," said Marc Stine, a Greek advocate hired by Boulder's Interfraternity Council.

Investigators believe the pledges were body slamming each other and in the processs, trashed the rooms.
