A third vehicle was involved in a tragic crash which claimed three lives in Cape Breton.

The new information was released Tuesday regarding the early morning collision in Mabou on July 20.

Two teens and a 71-year-old Utah man died while four others were taken to hospital with various injuries.

Police now say a youth was driving the third vehicle which hit into the others moments after the initial crash.

The cause has not been determined and investigation is still active.
