Working with our colleagues in An Garda Síochána we have now recovered a black BMW X5 which we believe was involved in the collision.
"The vehicle was located at an address in Co. Donegal on Monday evening and has now been recovered to a PSNI establishment for a forensic examination to be carried out. "
He added: "We are subsequently following a definite line of enquiry in relation to the collision and hope to progress our investigation in the near future.
