Deaths by heroin overdose in California

Timothy Charles Buckley III (February 14, 1947 – June 29, 1975) was an American musician. He began his career based in folk rock, but subsequently experimented with genres such as psychedelia, jazz, the avant-garde, and funk as well as unconventional vocal stylings. His commercial peak came with the 1969 album Happy Sad, reaching No. 81 on the charts, while his experimental 1970 album Starsailor went on to become a cult favorite. The latter contained his best known song, "Song to the Siren." Buckley died at the age of 28 from a heroin and morphine overdose, leaving behind sons Taylor and Jeff.

Michael Bernard Bloomfield (July 28, 1943 – February 15, 1981) was an American blues guitarist and composer. Born in Chicago, he became one of the first popular music stars of the 1960s to earn his reputation almost entirely on his instrumental prowess, as he rarely sang before 1969. Respected for his guitar playing, Bloomfield knew and played with many of Chicago's blues musicians before achieving his own fame and was instrumental in popularizing blues music in the mid-1960s. In 1965, he played on Bob Dylan's Highway 61 Revisited, including the single "Like a Rolling Stone", and performed with Dylan at that year's Newport Folk Festival.
Bloomfield was ranked No. 22 on Rolling Stone's list of "100 Greatest Guitarists of All Time" in 2003 and No. 42 by the same magazine in 2011. He was inducted into the Blues Hall of Fame in 2012 and, as a member of the Paul Butterfield Blues Band, was inducted into the Rock and Roll Hall of Fame in 2015.

Jan Paul Beahm (better known by his stage name Darby Crash, formerly Bobby Pyn; September 26, 1958 – December 7, 1980) was an American singer who, along with longtime friend Pat Smear (born Georg Ruthenberg), co-founded the punk rock band the Germs and was best known as their lead vocalist. In 1980, he committed suicide by overdosing on heroin.
