During an emotional sentencing at the Bronx County Hall of Justice on Monday, Vladimir Krull, a former police sergeant who was convicted of sexually abusing his girlfriend’s teenage daughter on three occasions, did not look at the complainant as she made a tearful statement to the judge.

Lester B. Adler, the acting Bronx Supreme Court justice, sentenced Mr. Krull to three years in prison for abusing the girl, who was 13 when Mr. Krull first kissed her on the mouth in September 2013, according to the district attorney’s office.

In January, a jury convicted Mr. Krull, 39, of eight criminal counts covering three encounters. Those included two instances of sexual intercourse with the girl — once in her home and once in his vehicle — and one encounter in which he demanded oral sex in his vehicle after taking the girl to a father-daughter breakfast at her school.

“I used to feel like I had endless options,” the victim, who is now 16, said. “Now I feel limited.”

Mr. Krull, dressed in an orange jumpsuit, kept his eyes mostly on the table in front of him while his ex-girlfriend and her daughter spoke. When the judge asked if he would like to say anything, he offered two words: “No, sir.”
