A Northbrook man arrested at his own wedding reception for slugging his new brother-in-law admitted guilt to misdemeanor battery Tuesday under a plea deal in which prosecutors dismissed seven felony weapons charges stemming from the same incident.

Sean T. Kelly, 26, of the 3500 block of Lawrence Lane, was sentenced to two years probation, fined $250 and ordered to undergo an anger evaluation under terms of the negotiated plea. He also was sentenced to 30 days in the McHenry County jail, but that already has been served since his July 26 arrest in Huntley.

In exchange for the guilty plea, county prosecutors dropped six counts of possession of a firearm without a valid firearm owner's identification card and one count of possession of ammunition without a FOID card filed after police arresting Kelly found three rifles, three handguns and 39 rounds of rifle ammunition in the trunk of his car.

The charges, which alleged Kelly could not lawfully possess the weapons because his FOID card had been revoked, were Class 3 felonies punishable by up to five years in prison.

Kelly's attorney, Senior Assistant Public Defender Richard Behof, noted Tuesday that it was his client who told police about the guns because he feared someone would take them from his car.

"He thought his card was valid and was doing the right thing," Behof said. "He didn't want to leave (the weapons) on the street. He was trying to be responsible."

Huntley police arrested Kelly after a brawl left several people bloodied and bruised during his wedding reception at a home on the 11200 block of Nicollete Lane. During the altercation, police said, Kelly punched a 30-year-old man later identified as his roommate and new brother-in-law, in the face.

Police said the brawl began when an exchange of words got out of hand. Many of those involved in the fight, police said, were intoxicated.

As officers arrested Kelly, police said, he asked if he could give his brother some items in the trunk of his car. Those items turned out to be the guns and ammunition, police said
