An adult man and a 9-year-old child died Friday after they were swept out to sea in the cold waters off the Golden Gate Bridge. 

The coroner's office released the identities of the victim's Saturday morning.

 The Marin County Sheriff's Office said Juan Escamillo-Rojas, 37, and his son Juan Carlos Escamillo-Monroy died after being swept out while fishing. They were both residents of San Francisco.

The U.S. Coast Guard found the two between Point Bonita and the Marin Headlands. A Coast Guard rescue boat and a Tiburon fire boat responded to the call for help, but with the water temperature a cold 53 degrees, the man and his son did not survive.

Officials says initially three people were swept out by the waters at Lower Fisherman’s around 4 p.m. Only one family member made it back to shore.

“It appears that one subject was able to get out of the surf and make a 911 call who coordinated the rescue units to a more precise location,” Randy Lavasseur, Law Enforcement Deputy Chief with the Golden Gate National Recreation Area, said.

A Tiburon fire crew headed to the area for training and the U.S. Coast Guard searched the cold  water and found the pair 25 minutes later.

Locals call Lower Fisherman’s “Black Sands Beach.” Signs at the trail head warn of dangerous conditions. Park police say the picturesque spot turns dangerous quickly.

“If you look at the terrain right now, it’s very rocky, uneven, it’s slippery,” Lavasseur said. “If you go down into the water’s edge, the tides can move up and down and even before you know it your feet are up in water and you can be climbing rocks because that tide moves up so quickly.”

Investigators are still piecing together exactly how the incident happened.

SAN FRANCISCO -- The latest battle for control of Alcatraz Island is under way.

Many have laid claim to the wind-swept rock in the middle of the San Francisco Bay since the last prisoner left the federal land in 1963. American Indians occupied the island for 19 months ending in 1972. And politicians have floated the idea of building a casino or even a new San Francisco 49ers football stadium on Alcatraz.

Today, the National Park Service and organizers of the America's Cup are tussling over Alcatraz's role in the Super Bowl of yacht racing. The island will offer some of the best views of the most prestigious competition when multi-million dollar boats take to the San Francisco Bay in 2012 and 2013. Alcatraz sits almost directly in the middle of the proposed race course and offers 360-degree views of the bay.

But the island already receives 1.4 million visitors a year and is at capacity during the summer tourist season. Therein lies one of the main sources of tension over how to balance competing priorities that arose when San Francisco was selected to host the 34th America's Cup contest.

The National Park Service manages the Golden Gate National Recreation Area, which includes Alcatraz and much of the race course. The city of San Francisco is in charge of satisfying environmental regulations, securing government permits and spearheading planning for the event.

The two got off to a rocky start when the city released a draft environmental impact report over the summer stating Alcatraz would be closed to the public and given over to well-heeled event sponsors and other VIPs for private viewing of the race. The report also made similar claims about Fort Baker at the foot of the Golden Gate Bridge. Both are popular tourist destinations.

"All lands and facilities in the Golden Gate National Recreation Area, including Alcatraz and Fort Baker, will remain open to the public throughout the entire period of the races," park officials declared in rejecting that proposal.

Today, the city's America's Cup project manager says the episode was a misunderstanding rooted in poorly written passages in the report.

Project manager Michael Martin said that organizers did discuss setting up private viewing areas for sponsors. But that idea was scrapped after park officials made it clear the America's Cup would have to abide by the same rules as the public when visiting the island.

The park service forbids any kind of seating — from bleachers to folding chairs — and limits picnicking to a dock area with obstructed views on Alcatraz. There are no food vendors on the island.

"There won't be any great accommodations," said park service spokeswoman Alexandra Picavet. "Because of that, Alcatraz may not be the best place to watch."

Park officials said America's Cup organizers will have to go through the same permitting process the public must go through to secure the prison for after-hours functions. Organizers plan to host parties in the prison's cell block in the evenings.

The America's Cup is expected to create 8,000 jobs and inject more than $1.4 billion into the region's economy during planning, construction and the actual racing, which will take place in a series of contests in 2012 and 2013. But the millions of spectators over that time— with 500,000 on peak days_will test the Bay Area's transportation network, sanitation systems and the environment during about 50 days of racing.

The city's draft environmental impact report, which lays out the preliminary plans for the races and the proposed precautions to be taken to protect the environment, drew comments and concerns from 34 public agencies, 41 non-governmental organizations and 115 individuals. The report, the comments and the city's responses will be presented to the San Francisco Planning Commission on Thursday. No construction can began until the commission approves the report, and its decision can be appealed to the San Francisco Board of Supervisors.

The National Park Service's comments and concerns over the environmental impact run 22 pages. One concern was the potential impact of 80,000 people descending on historic Crissy Field, which has a beach and a newly restored wetland.

The park service also said the city has failed to explain "how ferry traffic to and from Alcatraz would be maintained, and what impacts would be to visitors attempting to visit the island." It noted that ferry service "currently runs every 30 min. through what would be the race area."

In response, the city said it would work with the U.S. Coast Guard and the ferry service to ensure safe passage during the races.

The park service is also concerned about how organizers plan to protect birds, marine mammals and plants. The city said it will prohibit America's Cup-related boats from coming within 100 yards (90 meters) of Alcatraz and barring helicopters from getting any closer than 1,000 feet (300 meters).

"In our experience, it is not realistic to believe that all events will proceed as planned around Alcatraz and that sensitive areas and closures will be adequately enforced," the park service responded in asking for bigger buffer zones.

Both sides say they are continuing to negotiate.

"We are still in a dialogue with the park service," said the city's project manager Martin. "We are taking their concerns very seriously."
