(Gladstone, OR) -- The search is over for a 25-foot tugboat that went missing after sinking in the Willamette River earlier this month. The U.S. Coast Guard says crews found the boat near Meldrum Bar Park in Gladstone on Friday. The boat has been missing since December 13th, when it sank while helping a barge near the I-205 bridge. No leakages have been reported, but crews are taking steps to protect the environment in case anything does leak from the boat.
