The search was halted Tuesday morning for a potentially distressed woman whose mysterious call the previous night had the U.S. Coast Guard canvassing Bay waters near Tiburon.
The call came around 8 p.m. Monday, authorities said.
“Listen to me, listen to me,” the woman said. “I have a mayday.”
The Coast Guard used tracking technology to locate where the call may have come from. The device homed in on an area near Tiburon, though the technology is not so precise that it can tell whether the distressed woman was calling from land or water, authorities said.
The Coast Guard sent a Yerba Buena Island-docked 87-foot cutter and a 25-foot response vessel to search the waters, but found nothing Monday night, Petty Officer Pamela Manns said. A subsequent search Tuesday morning, which included the use of a Coast Guard helicopter, also produced no results, officials said.
The search, which has been called off indefinitely, saturated the area from the Richmond Bridge to Angel Island and beyond, officials said.
The Coast Guard would not speculate on whether the call was a hoax.
However, calls to tugs and commercial vessels that were in the area soon after the distressed call produced no clues, officials said. There were also no recreational vessels found in the area Monday night, they said.
