Miller was among 20 family members and friends from the Stockton and Sacramento areas who had gathered to scatter the ashes of Maria Boisa, a Fremont nurse who died 10 years ago at age 32.

The group had spent about three hours at Angel Island’s Ayala Cove before heading back toward shore when rough afternoon conditions and a powerful swell caused the top-heavy boat to roll onto its side, rapidly take on water and sink.

Sixteen people were rescued, including three who suffered injuries. 79-year-old Clifford Joseph Boisa, a retired Sutter County reserve deputy, also died in the tragedy.

Two people remain missing and are believed to be trapped inside the sunken vessel, which rests about 120 to 130 feet below the surface west of Alcatraz Island.

Madruga was a friend of Maria, according to the San Francisco Chronicle.

In a Facebook statement shared by Quin Madruga, the family said they were “heartbroken by the loss of our beloved mother, daughter, sister, and aunt, Tondra Madruga.”

They asked for privacy as they grieve, saying, “Our hearts remain with every family impacted,” while thanking the public for its kindness and understanding.
