'Beloved' mom's body recovered after boat capsized near Alcatraz Island in San Francisco Bay
SAN FRANCISCO (KGO) -- The body of a 58-year-old woman has been recovered after a boat capsized and sank near Alcatraz Island in San Francisco Bay, marking the second person confirmed dead from the incident.
The San Francisco Medical Examiner's Office identified the second victim as Tondra Madruga of Sacramento County. Two people remain missing.
Madruga's relatives said in a statement that they're "heartbroken by the loss of our beloved mother, daughter, sister, and aunt."

"Our hearts remain with every family impacted, and we sincerely appreciate your kindness and understanding," the family said. "We extend our heartfelt thanks to the U.S. Coast Guard, the San Francisco Fire Department, the San Francisco Police Department, all of the first responders, and the civilian boaters and community members who selflessly assisted in the search and rescue efforts. Your dedication and support mean more to our family than words can express."
The owner of the boat, John Boisa, says that she was a family friend.
John Boisa's 79-year-old brother, Clifford Boisa from Sutter County, was identified on Wednesday as the first person confirmed dead from the disaster.
Many of their family members were among the 20 people on board Tuesday, setting out to spread a relative's ashes.
John Boisa told ABC7 Eyewitness News his sister Carol and Clifford's wife Jackie are the two other people still missing.
The U.S. Coast Guard suspects a large wave may have overtaken the boat- though investigators will likely need to recover the vessel to confirm a cause.
San Francisco firefighters say they will probably need outside help to find the boat and raise it from the bottom of the bay.
