The company whose charter bus was involved in a collision in Nova Scotia that killed one person says all those injured in the crash have returned home.

Pennsylvania-based Executive Coach Inc. says it is contacting each of the passengers to arrange in-person meetings to discuss their personal needs and offer assistance.

Vice-president Dale McMichael says a memorial service for 70-year-old Joyce Bowers of Ephrata, Pa., who died in the crash, was held in her hometown on Tuesday.

He says the investigation into the July 13 crash on Cape Breton's Cabot Trail that injured 10 other people is ongoing.

The bus was carrying 21 people, including the driver, on a 10-day Maritime tour when it went off the road on the Cabot Trail highway south of Neil's Harbour and landed on its side.

The Mounties have ruled out mechanical failure as a contributing factor.
