Nova Scotia RCMP say no charges will be laid after a bus crash on the Cabot Trail in July killed a 70-year-old woman from Pennsylvania.

After their investigation and mechanical inspection of the bus, the police concluded the driver fell asleep.

On July 13, 2014, RCMP were called to a section of the trail about three kilometres from the community of Neils Harbour. The tour bus, with 21 people on board, left the road and rolled into a ditch at about 2:30 p.m.

Bill Westlake, who owns the company that organized the trip from the U.S. to Nova Scotia, was driving the bus. During the crash, he was thrown through the front windshield and injured.

At least 18 people were injured including Joyce Bower, of Lancaster County in Pennsylvania.

She was taken to hospital where she later died.
