State authorities are investigating an industrial accident that led to the death of a Klamath Falls man during the weekend. On Monday, Oregon Occupational Safety and Health Administration (OSHA) confirmed it is investigating the death of Francis “Frankie” Crispen Jr., 28. Crispen was found dead Saturday at Columbia Forest Products, in Klamath Falls, where he was employed. OSHA spokesperson Aaron Corvin said he was not able to comment on the specifics of the incident. He said it is likely their investigation will conclude in the next three to four months, after which a report detailing their findings will be made public. Jeff Moresi, human resource manager for Columbia Forest Products’ Klamath Falls location, said they are working closely with OSHA during the investigation. Moresi said the fatal incident occurred Friday evening, but he did not yet have further information.
