CORVALLIS, Ore. (AP) — Police say a former chiropractor from Corvallis is under investigation for allegedly secretly taping patients during examinations. KOIN-TV reports the patients were women in their 20s and 30s, according to the Corvallis Police Department. Detectives working the investigation into Dr. William O’Donnell’s conduct said they recently received information indicating secret recordings took place between November 2013 and 2014 at Vertebrata Chiropractic. Any female patients of O’Donnell are urged to contact police. Vertebrata is no longer in business and a call to the business was met with a number out of service message.
