Two friends who headed out on a late-night canoe trip to witness the Bay Area’s striking bioluminescent waters were later found dead, officials said.
Casey Flynn Melia, 36, and a second person whose name has not been released were discovered Sunday at about 1:30 p.m. after setting off around midnight on Tomales Bay, a narrow coastal inlet in Marin County, California.
The unidentified man was found in the water, while Melia was located on shore just north of Hog Island, NBC Bay Area reported.
Both men were pronounced dead at the scene.
Authorities said Melia, who lived in San Francisco, and his friend had been wearing life jackets during the outing.
They were reported missing after they failed to return from their trip as planned, the Marin County Fire Department told the San Francisco Chronicle.
The details of what led to their deaths remain unknown. The investigation is being led by the Sonoma and Marin County Sheriff’s Offices.
Melia’s official cause of death is pending. Routine toxicology testing and a post-mortem examination are scheduled for later this week, the Marin County Sheriff’s Office said.

Tomales Bay is known for its dangerously cold water, hazardous conditions near the sandbar and the mouth, and strong afternoon winds.
The friends had planned to camp at White Gulch Beach, which is located directly on the western shore of Tomales Bay, according to the Chronicle.
They ventured into the water to witness the annual bioluminescence, a phenomenon that is sometimes visible along the bays and coast in California.
The spectacle takes place when the small organisms in algae, known as dinoflagellates, bloom after they become agitated.
The tiny organisms emit flashes of light through a chemical reaction with a molecule called luciferin and an enzyme known as luciferase, causing a vibrant blue color to glow in the water.
Bioluminescence takes place every year from June to October in Tomales Bay.
The phenomenon also takes place in other locations across the US, including the Outer Banks, North Carolina.
It also occurs in Vieques, Puerto Rico; Space Coast, Florida; San Diego, California; San Juan Island, Washington; Gulf Shores, Alabama; Tybee Island, Georgia; and Kona, Hawaii, according to Travel + Leisure.

Bioluminescence occurs most commonly among squid, fish, and ‘gelatinous zooplankton’, the National Oceanic and Atmospheric Administration (NOAA) said.
The ‘gelatinous’ species include jellyfish, comb jellies, siphonophores, and other sea animals that are mostly made of water, the agency added.
