A teen showing off a gun at an underage drinking party Tuesday in Beach Park accidentally shot another partygoer, according to the Lake County sheriff's office.
Deputies responded to the shooting just before midnight at a home on the 38000 block of North Pine Avenue.
Police say Charles W. Walkanoff, 19, who lives at the residence, was showing off the Billerica 9 mm handgun when it went off, wounding a Waukegan girl in the abdomen.
The girl was taken to Vista Medical Center East, where she underwent surgery and was in stable condition, Lake County Sgt. Sara Balmes said.
Walkanoff was charged with aggravated battery of a firearm, reckless discharge of a firearm, aggravated unlawful use of a weapon, no FOID card and reckless conduct.
His bond was set at $250,000, and he's next expected in court Jan. 24.
Three other partygoers were charged with underage consumption of a minor: Alex A. Spencer, 19, of Beach Park; Justin L. Jones, 18, of Beach Park; and an unidentified minor.
