WHEATON, Ill. (AP) _ Six teenagers pleaded guilty to partying in a suburban Chicago home while the owners were on vacation, and agreed to repay the $40,000 in damage.

The teens pleaded guilty to trespassing and property damage.

Police said a family friend used a security code to enter the home in April and a two-day party began. While responding to a noise complaint, police found blood smeared on the walls, broken pictures and safes, ruined carpet and closets ransacked, prosecutor Michael Botti said at the hearing Wednesday.

Richard Sullivan, 18, who pleaded guilty, said he thought it was a typical spring break party until people started shooting arrows into walls and walking out with VCRs.

Also pleading guilty were Christopher Cundari, 18; Nicholas Carbonara, 17; Crystal Dunbar, 18; Bradley Lietske, 18; and Merchant Long, 17. Another teenager already pleaded guilty to trespassing.

Each was sentenced 30 to 40 hours of public service, and some agreed to attend substance abuse evaluations.
