WORCESTER, Mass. — A man from Ecuador convicted of dragging a Milford motorcyclist to his death under his pickup truck has been sentenced to up to 14 years in prison.

A judge Monday sentenced 37-year-old Nicolas Dutan Guaman after clearing him of a second-degree murder, but convicting him on other charges including vehicular manslaughter in the August 2011 death of 23-year-old Matthew Denice.

Prosecutors say Guaman was drunk and driving without a license when hit Denice’s motorcycle. Denice was dragged even as witnesses banged on the side of Guaman’s pickup. The death sparked a debate in Massachusetts about immigration enforcement.
