The body discovered Thursday floating near Treasure Island has been identified as one of the three people still missing after a boat capsized earlier this week<\/a> in the San Francisco Bay.<\/p>\n

Tondra Miller, 58, was among 20 people thrown into the bay earlier this week when a wave hit their three-story boat<\/a> off as it motored near Alcatraz Island, according to the San Francisco Office of the Medical Examiner. The Sacramento County woman is the second person confirmed dead in the disaster, while two others remain missing.<\/p>\n

Also killed in the sinking was Clifford Boisa, 79, the brother of John Boisa, who was the vessel\u2019s owner and operator.<\/p>\n

In a Facebook post, a person who said they were a relative identified her as Tondra Madruga, and said her family was \u201cheartbroken by the loss of our beloved mother, daughter, sister, and aunt.\u201d The post thanked first responders and the civilian boaters who rushed to help people cast into the bay on Tuesday, adding that \u201cyour dedication and support mean more to our family that words can express.\u201d<\/p>\n

The family also thanked people for privacy, and said \u201cour hearts remain with every family impacted, and we sincerely appreciate your kindness and understanding,\u201d said the post by Quin Madruga.<\/p>\n

John Boisa identified the other two people still missing as his sister, Carol Boisa, as well his sister-in-law \u2014 and Clifford Boisa\u2019s wife \u2014 Jackie Boisa.<\/p>\n

Clifford and Jackie Boisa were planning to celebrate their 50th wedding anniversary in November, according to a GoFundMe post<\/a> for a fundraiser to support Clifford\u2019s daughter, Mary Ann Boisa.<\/p>\n

All of them were on the 49-foot boat, called the Volare, when a wave hit the craft around 3:30 p.m. Tuesday, causing it to list to one side before rolling over. Sixteen people were plucked from the water by emergency crews and by multiple private boaters who arrived on scene first and were later hailed by San Francisco Mayor Daniel Lurie for their \u201cheroic\u201d actions.<\/p>\n

The boat had been on a \u201cfamily outing\u201d that day, John Boisa told this news outlet, that included spreading the ashes of a family member who had died years ago. The boat tracking website VesselFinder showed the boat leaving the city\u2019s Marina Yacht Harbor\u00a0around 10:15 a.m. Tuesday and traveling beneath the Golden Gate Bridge into the Pacific Ocean, before turning around off Lands End and visiting Angel Island.<\/p>\n

The boat appeared to be chugging back in the direction of the harbor when it sank.<\/p>\n

The Coast Guard searched for survivors over 950 square nautical miles \u2014 an area larger than the size of Yosemite National Park \u2014 before ending the rescue operation Wednesday evening.<\/p>\n
