A San Francisco man has been convicted of murder and mayhem for using a meat cleaver to castrate and kill his father, whom he blamed for coddling him and fostering his drug addiction, authorities said Tuesday.

After deliberating three days, a San Francisco jury on Monday found Jan Erickson, 28, guilty of second-degree murder and aggravated mayhem in the Oct. 10, 2004, attack on Stephen Erickson, 65.
Residents of the Graywood Hotel on Mission Street heard the father's screams for help in the midst of the savage attack. He was stabbed 37 times, castrated and his eyes stabbed in a case that police said was one of the most horrific crime scenes in recent memory.
