A Milford basketball coach at the center of a sexual assault investigation faced a judge Monday.

Robert Dulin is accused of having a two-year affair with a 16-year-old girl he coached at summer basketball camp. During the investigation, Superintendent Dr. Gregory Firn wrote a letter of recommendation on Dulin?s behalf. The letter sparked a controversy that included Mayor Jim Richetelli (R-Milford) asking Firn to consider resigning.

Dulin entered pleas of not guilty and is due back in court on July 6.
