A 19-year-old Manassas man has been charged with shooting another teenager outside a Friday night party at the National Guard Armory near Leesburg.

Gordon Lawrence Tibbs Jr., of the 9400 block of Taney Road, was a guest at the private party when he allegedly fired shots at another partygoer about 2 a.m. Saturday during a fight in the parking lot, according to Deputy Doug Taylor, a Loudoun County sheriff's spokesman.

The victim, Charles M. Forbes III, 19, was shot in the arm, according to charging documents filed in Loudoun County General District Court. Forbes was treated at Reston Hospital Center and released, Taylor said. Investigators would not say where Forbes lives.

Tibbs, who works for a cousin's Manassas-based moving company, initially declined to speak to deputies who arrived at the armory, according to the charging documents. He later said he fired a gun twice in the air to "clear the lot," the documents said.

A .380-caliber handgun was found in the trunk of Tibbs's car, and rounds consistent with that type of weapon were found in the parking lot, according to the court documents.

Taylor said that several fights occurred during the party and that the shooting was sparked by a scuffle that started inside the armory and moved outside. Investigators would not say why they believe the fight started or who was involved.

Forbes told investigators that he was "caught in the cross-fire," the charging documents stated.

Taylor said the armory was rented by a Winchester man for the evening. He said investigators do not know how many guests attended.

Tibbs is charged with felony counts of shooting with the intent to maim, use of a firearm while committing a malicious wounding and discharging a firearm in a public place. He also is charged with carrying a concealed weapon without a permit, a misdemeanor. The combined charges carry a maximum sentence of 29 years in prison. Tibbs is being held in the Loudoun County Adult Detention Center without bond. He is scheduled to appear in court Jan. 25. A woman who answered the phone at his home declined to comment.

Sheriff's investigator Ken Fognano is asking anyone with information on the shooting to call his office at 703-858-2921.
