David had third-degree burns over 90% of his body; he required finger and toe amputations[7] and received a total of more than a hundred skin grafts.[8] He was badly disfigured and during one grafting operation experienced brain swelling that led to seizures and other complications.[9] Charles Rothenberg, who stated that he had originally intended to kill himself as well as his son, was sentenced in July 1983 to 13 years in prison, the maximum permitted at the time for his offenses;[9] guidelines were changed as a result of the case.[4] He was released in 1990 on three years' supervised parole after serving seven years.[8][10] After two years he fled, but turned himself in to authorities.[11] In 1996 he was tried for a shooting in Oakland,[12] at which time Dave, then 19, visited him in prison;[8][9][13] he read a statement to him in which he stated that Charles Rothenberg was "not a father but an imposter".[6] In 1998 Charles Rothenberg changed his name to Charley Charles, and in 2007, after also being convicted of various offenses in two other states,[6] under California's three strikes law he was sentenced to 25 years to life for weapons offenses in San Francisco.[3][13]
