Brian Scott Card, 19, of Van Nuys, California, was one of four teenage boys shot to death while camping in Henry Cowell Redwoods State Park in Felton, Santa Cruz County, on February 10, 1973. The other victims named in the case were Robert Michael Spector, 18, also from Van Nuys; David Allan Oliker, 18, of Sherman Oaks; and Mark John Dreibelbis, 15.

Their remains were found about a week later. Mullin, described as having a history of serious mental illness and violent behavior, was arrested and charged in these killings; he was later convicted and received life terms.

Does anyone have memories or information about the victims, their time in Santa Cruz County, or that stretch of Henry Cowell Redwoods State Park in February 1973?
