Linda L. Burke, a Potomac High School teacher arrested June 11 in an assault on a state police investigator, was found dead in her home Sunday in an apparent suicide.
Burke, 40, had been under investigation by state police for alleged misconduct with a minor.
She died of what appeared to be a self-inflicted gunshot wound, said Prince William police spokesman Jonathan Perok. There were no signs of foul play, he said. The case is being classified as a death investigation pending the state medical examiner's report.
Burke, who lived on Goshen Court in Manassas, was arrested earlier this month during an interview with a state police special agent. She was charged with felony assault on law enforcement and obstruction of justice. She had not been charged in connection with improprieties with a minor.
State police are investigating the alleged misconduct because Burke was married to a Prince William police officer. State police spokeswoman Corinne Geller said the case remains open.
Burke, an English as a Second Language teacher at Potomac, was released from police custody shortly after her arrest.
She had been a teacher with Prince William County schools since 2003 and was on administrative leave pending outcome of the investigation, school officials said.
