MILFORD - A Bridgeport man pleaded not guilty yesterday in the stabbing death of a teen in Milford.

Police say Philip Mocrease, 32, stabbed Ryan Simpson, 19, at a party in March.

Police believe the stabbing was the result of a $50 drug debt Simpson owed Moncrease.

Moncrease's 17-year-old girlfriend is also charged with assault in connection with the case.
