NEW YORK — A New York City police sergeant was convicted Monday of raping and sexually abusing his then-girlfriend’s 13-year-old daughter.

Prosecutors said Vladimir Krull’s abuse of the girl started in September 2013, when he kissed her on the mouth. A jury determined he had sexual intercourse with her on two separate occasions in the following months, and in a third incident in June 2014, “directed the teen to perform oral sex on him in his vehicle after a Father/Daughter breakfast for her eighth grade class,” according to a statement released by Bronx District Attorney Darcel Clark.

“The defendant horrifically abused the trust of this family and engaged in sexual acts with a child,” Clark said in the statement.

The jury deliberated for five days after Krull’s four-week trial. He faces up to seven years in prison for each incident.

Krull was fired from the police force on Monday, reports the Wall Street Journal.
