Authorities say Montances left his home with a canoe on his truck on Tuesday at around 1 p.m. and never returned. He was last seen preparing to launch the vessel, which the Hercules Police Department described as a green, single-rider canoe.

His vehicle was later found at Bay Front Park in Pinole, the United States Coast Guard said. Search and rescue crews scoured more than 280 square miles over 38 hours looking for Montances, according to authorities, but failed to find him.
