A New York state man has pleaded guilty to one count of first-degree sodomy for having oral sex with a 15-year-old girl during the final hours of last summer's Woodstock '99. The conviction of Timothy Weeden, 27, of Rome, NY, comes six months after the disastrous upstate New York music festival ended in riots, fires and looting.

On July 26, 1999, Weeden forced the girl to perform fellatio behind a convenience store located across the street from one of Woodstock's main gates. The girl reported the asasult to the Rome police, who contacted the county's Child Sexual Abuse Task Force.

Besides the charge of the first-degree sodomy, which involves the use of force, Weeden had been indicted on one count each of third-degree sodomy, first-degree sexual abuse and endangering the welfare of the child. Those charges were dropped in exchange for his guilty plea, according to Weeden's lawyer, who specializes in sex-offender cases.

The lawyer said that Weeden would probably not get the maximum penalty of 25 years because he was a first-time offender. He will be sentenced on Feb. 25.

Weeden was a prison guard at the the Midstate Correctional Facility in Marcy, NY. After he was arrested, he was suspended without pay. He resigned from his post on Aug. 30 as a result of the charges, according to the prison's personnel department.

The New York State Police are still investigating five reported charges of rape in connection with the concert. There have been no arrests in those cases.

Lt. Jamie Mills said that "the people heading those investigations are still hopeful that there will be arrests," but she acknowledged that because the festival attendees grew to an estimated 150,000 people over three days and then disbanded to their home states, finding new leads is difficult.

In other Woodstock-related incidents, Keith G. Cook, 24, of Maine, and Jennifer E. Staas, 20, of Georgia, were found guilty in charges related to stealing a car from the Woodstock parking lot on July 25, 1999. Cook was convicted of grand larceny, credited for time served in the New York's Oneida County jail and sent to Georgia where he had a parole violation. Staas was convicted of possessing stolen property, served four months in Oneida County jail and was released on Dec. 20.

Last October, ten New York State Police troopers and two supervisors were given suspensions and censures for two separate incidents in which police asked female concertgoers to take off their clothes. In one incident, two nude women posed for photographs with a group of police. In another, a group of topless women washed a state police car, an event captured in a New York Post photograph.
