State Police are investigating two crashes that killed a pair of motorcyclists in Seekonk and Milford on Monday, officials said.

The first crash was reported on Interstate 495 in Milford just before 4 p.m. On arrival, state troopers discovered that a motorcyclist, identified as Lane Prescott, 51, of Weare, N.H., had lost control of his 2010 Harley-Davidson while traveling south and crashed just before Exit 19, State Police said in a statement.

Prescott was taken to Milford Regional Medical Center, where he was pronounced dead.

No other injuries were reported.

Officials closed the center and left lanes until 5:30 p.m., creating a 9-mile traffic delay, State Police said.


The second crash involved a car and a motorcycle on Interstate 195 in Seekonk at 9:55 p.m.

A preliminary investigation indicated the driver of a 2012 Suzuki motorcycle had been traveling east when he struck a 2003 Nissan Altima from behind, causing him to lose control and crash, State Police said.

The motorcyclist, identified as Frederick Hoard III, 24, of Attleboro, was taken to Rhode Island Hospital, where he was pronounced dead.

The driver of the car, a 58-year-old man, and his passenger, a 50-year-old woman, were uninjured, State Police said.
