A former music teacher from Bethesda who state police arrested in May has been indicted on federal child pornography charges.

Charles Victor Kopfstein-Penk, 74, was indicted Thursday in U.S. District Court, the United States Attorney’s office said in a press release.

Kopfstein-Penk was arrested May 23 after state police searched his home on Lone Oak Drive. They said they recovered numerous electronic devices that contained child pornography. The state police obtained a search warrant after they started investigating Kopfstein-Penk in February.

Kopfstein-Penk, who gave music lessons out of his home, had images that included the sexual abuse of children, including one of child pornography that involved a pre-teen, according to the indictment.

The indictment also seeks “the forfeiture of any property traceable to profits from the offense or used to commit the offense, including a desk top computer and five external hard drives.”

He could face up to 20 years in prison.

Kopfstein-Penk’s attorney, William C. Brennan Jr., was not available for comment Friday morning.

Kopfstein-Penk also faces multiple charges of child pornography possession in Montgomery County Circuit Court, according to state court records. He is scheduled for a three-day jury trial Oct. 29.

Steve Chaikin, his attorney representing him in circuit court, was not available for comment Friday morning.
