LONGVIEW, Washington (From The Daily News) -- Federal regulators have opened an investigation into the accident that critically injured a longshoreman aboard a ship at the Weyerhaeuser Co. log dock Tuesday.

Representatives from Occupational Safety & Health Administration (OSHA) were in Longview Wednesday interviewing people close to the incident, the agency confirmed. The investigation could take up to six months to complete, an OSHA spokesperson said.

The worker was hired by S.S.A. Pacific to load logs and was not a Weyerhaeuser employee.

Neither the victim's name nor an update on his condition were released Wednesday.
