San Francisco: A crewman from a towboat was still missing on Monday after the vessel sank in the Mississippi River on Sunday.
The 61-foot towboat Charlie Boy capsized on Sunday evening on the Upper Mississippi near St Louis and two of the three-man crew were recovered, uninjured, by a nearby tugboat after being in the water for about 10 minutes.
US Coast Guard (USCG), emergency responders and volunteer private tugboats were working to find the missing man, who was not named by late on Monday. A section of the river was closed and a roughly 40-mile stretch was being searched.
And the US Army Corps of Engineers was assisting in efforts to find the boat, which had a fuel load of approximately 9,350 gallons of oil and other fuels on board.
USCG pollution responders reported no signs of spillage as of Monday night.
A spokesman for St Louis Fire Department said the sinking happened after the tugboat collided with a barge on Sunday evening.
