CENTRAL ISLIP, N.Y. (CBSNewYork/AP) — A Long Island man has pleaded not guilty to charges he struck and killed a 24-year-old woman.

Preston Mimms of Mastic was charged with leaving the scene of the July 29, 2011, accident.

The victim, 24-year-old Erika Hughes — a single mother of a 15-month-old girl — was walking on Mastic Road in Mastic Beach just before midnight when she was struck, police said.  The impact threw her body against a curb.

Police said Mimms fled the scene without so much as slowing down.

Mimms was arraigned in Suffolk County District Court on a grand jury arrest warrant. He’s being held on $250,000 cash bail.
