Two Bay Area men reportedly drowned in Hawaii Friday.
While vacationing on the beach in Kauai Island, a strong wave knocked Baker down, dragging him out to sea. Griffiths dove in to save his friend, however, he was unsuccessful.
Rescuers located Griffiths' body, but Baker's has not been found.
"The water was just so rough there was no way he could get himself back to land and back out of the water," Kauai County Communications director Beth Tokioka told KTVU.
The men were "inseparable," according to the San Francisco Chronicle. They shared a love for music, travel and water. Their vacation to Hawaii was in celebration of Griffiths' birthday -- he would have turned 47 on Saturday.
Forty-seven-year-old Baker lived in Vallejo and worked as a music therapist for special needs children. His musical talents included guitar, piano, didgeridoo and percussion. Friends said he had a big heart and an ability to connect with anyone.
Griffiths, an Australia native living in San Francisco, owned a mobile-app company. Friends described him as a "vibrant" and "smart" man with a knack for engaging with strangers. He was engaged to 39-year-old Jennifer Kwong.
"He's a very lovable man," Kwong told the San Francisco Chronicle. "I'm in shock. I lost my fiance and a really good friend."
