The San Francisco Bay boat sinking that killed at least two people and left two others missing has claimed a second identified victim: a 58-year-old woman from Sacramento County whose body was recovered Thursday afternoon.

The Office of the Chief Medical Examiner identified her as Tondra Miller, who also went by the last name Madruga. Her Facebook profile listed Folsom as her home.

She was among 20 people aboard a vessel that went down near Alcatraz Island earlier this week.

How She Was Found

San Francisco police had been running sonar scans of the bay when the discovery happened almost by accident.

Shortly after 1 p.m. Thursday, someone aboard a passing boat spotted a body in the water near Treasure Island and flagged down officers. Crews pulled her from the bay, and she was pronounced dead at the scene.

The recovery came days after the sinking itself and offered the first resolution for one of the families still waiting for answers.

Remembering Tondra Madruga

The people who knew her have been describing the same thing over and over: warmth that landed immediately.

Leanne Mis-Dial met her when they were teenagers at a football game. The friendship stuck, built on shared interests that kept them outdoors — horseback riding, dirt biking, and time spent away from anything resembling a schedule. Decades later, she’s still calling Madruga one of the most openhearted people she ever knew, someone who gave affection freely to anyone who crossed her path.

Donte Harrison, a friend of Madruga’s son, remembered her home more than anything else. He described the feeling of walking through her door — a sense of ease that never wavered, the kind of comfort that comes from someone who genuinely wants you there. He called her one of the most loving mothers he’d ever encountered.

Her Family’s Statement

On Thursday night, Madruga’s family posted a statement to Facebook acknowledging the attention the accident has drawn and asking for space to grieve.

They described her as a mother, daughter, sister, and aunt, and said their hearts remain with every family caught up in the tragedy — not only their own. The statement thanked the U.S. Coast Guard, the San Francisco Fire Department, the San Francisco Police Department, and every first responder involved.

They also singled out something that often goes unmentioned in official accounts: the civilian boaters and ordinary community members who joined the search without being asked. That help, the family wrote, meant more than they could put into words.

The First Victim Identified

A day earlier, authorities named the first confirmed death in the incident.

Clifford Joseph Boisa, 79, of Sutter County, was identified Wednesday. His wife, Jackie Boisa, and his sister, Carol Boisa, remain missing as of Friday.

The Sutter County Sheriff’s Office confirmed that Cliff Boisa had served as a retired reserve deputy, spending 14 years with the department from 1987 through 2001. The office issued condolences to his family.

Three members of one family were aboard. Only one has been recovered.

What Happened on the Water

San Francisco Fire Lt. Mariano Elias described the vessel as a Volare cabin cruiser registered out of Stockton. It stood roughly three stories tall and measured close to 50 feet in length — a substantial boat, not a small pleasure craft.

Investigators believe it departed from the Saint Francis Yacht Club in San Francisco.

The detail that has struck many people following the story is why everyone was on board in the first place. The passengers had gathered for a memorial service. A group assembled to honor someone who had died ended up at the center of another tragedy.

Sixteen of the 20 people aboard were rescued. Two have been confirmed dead. Two remain unaccounted for. A dog on the boat also died.

The Search Continues Under Difficult Conditions

The U.S. Coast Guard suspended its search for survivors on Wednesday night, a decision that typically reflects the grim arithmetic of water temperature and elapsed time rather than any lack of effort.

San Francisco police pressed on Thursday, continuing to look for the missing and working to recover wreckage from the vessel.

That recovery faces a serious obstacle. The Coast Guard estimates the boat is resting roughly 130 feet below the surface. Divers are still attempting to reach it, but conditions become significantly more dangerous past the 120-foot mark. At those depths, dive times shorten dramatically, decompression requirements multiply, and the margin for error narrows to almost nothing.

The bay itself compounds the problem — strong currents, limited visibility, and cold water make even routine operations difficult.

What Remains Unanswered

The central question hasn’t been addressed publicly: what caused a nearly 50-foot cabin cruiser to sink in familiar waters near one of the most heavily trafficked stretches of the bay.

Until the wreckage is located and examined, that answer stays out of reach. Investigators will want to look at the vessel’s condition, how it was loaded, weather and water conditions at the time, and whatever accounts the 16 survivors can provide.

For the families involved, those findings matter less right now than the search still underway. Two people are unaccounted for. Their families are waiting for the same call the Madruga family received Thursday — the one that ends the uncertainty, even as it confirms the worst.
