Local police say a medical problem may have triggered a fatal crash involving a 71 year old La Pine man yesterday morning. Deschutes County Sheriff's officials say Robert Currin, 71, died when his SUV ran off of Burgess Road in La Pine. Witnesses said Currin’s explorer suddenly left the road, going off the north side and coming to rest in dense willow bushes, less than two feet from the river. Currin was pronounced dead at the scene of the crash. He was wearing his seat belt at the time of the crash and the airbag did deploy.
