Two more students have accused a Montgomery County fifth-grade teacher of sexually abusing them at Meadow Hall Elementary School in Rockville, police said.

Timothy V. Krupica, 30, of Glen Dale, W. Va., turned himself in Monday at the Rockville police station after the new charges were brought against him and a police warrant was issued for his arrest, according to Montgomery County police spokeswoman Rebecca Innocenti.

Two students, both 11-year-old girls, told police that Krupica had fondled them outside their clothes and forced them to touch him inappropriately, Innocenti said.

Their accounts are similar to those of two other students who told police in February that Krupica had sexually abused them. All of the alleged incidents occurred during school hours between September and February. The new charges are part of an ongoing investigation against Krupica, police said.

Krupica was released from Montgomery jail Tuesday morning after posting $100,000 bail. He is scheduled to appear in court on April 26.

“I’m definitely shocked to hear about new charges, and I’m sad to hear about new charges,” said Carol Gangnath, whose son is in Krupica’s fifth-grade class. “He is one of the most popular and well-loved teachers at Meadow Hall. I’m confident that the legal process will result in a positive outcome for him and his family, and that the truth will come out.”

Krupica’s attorney, Jeffrey Harding, declined to comment. Krupica is on administrative leave with pay from Meadow Hall while the investigation continues.

Krupica has been charged with four counts of sexual abuse of a minor, five counts of third-degree sex offense, three counts of fourth-degree sex offense, and one count of attempted third-degree sex offense, police said.
