A tractor-trailer driver from Miller Place was arrested after, police said, he struck and killed a woman riding a bicycle while he was high on drugs Wednesday morning in Maspeth, Queens.

The NYPD said Dennis Forceri, 57, of 476 Harrison Ave., was arrested after an investigation into the fatal collision, which occurred in a warehouse district near 56th Road and 48th Street about 8:45 a.m. The woman, identified as Anna Rodriguez, 34, of Ridgewood, was pronounced dead at Elmhurst Hospital Center.

Police said 108th Precinct officers responding to a 911 call found Rodriguez unresponsive in the roadway with "trauma to her head and body." An investigation by the NYPD Highway Division's Collision Investigation Squad determined the tractor-trailer, driven by Forceri west on 56th Road, made a right turn onto northbound 48th Street -- striking the bicyclist, who was heading west.

Police did not immediately name the company that owned the tractor-trailer dump truck.

In addition to being charged with first-degree vehicular manslaughter, criminally negligent homicide and driving while ability impaired by drugs, police said, Forceri was charged with third-degree aggravated unlicensed operation of a motor vehicle and with failure to yield to a bicycle and failure to exercise due care.

He had not been arraigned Thursday night and remained in a hospital on a medical issue, a spokeswoman for the Queens district attorney's office said, adding the "matter is still under investigation."
