OAKLAND — A computer support employee was sentenced Thursday to 10 years in prison for downloading child pornography into two of his work computers, according to officials.
A forensic examination of David Busby’s computers recovered about 1,400 images of child pornography that had been deleted, said federal prosecutors.
Busby,61, worked at Lawrence Berkeley National Laboratory and part-time at National Energy Research Scientific Computing Center, which is affiliated with National Laboratory, officials said.
Evidence at trial showed that on April 20, 2010, a network security analyst detected internet traffic indicative of child pornography on the National Energy Research Scientific Computing Center computer network. The internet traffic was isolated to a single laptop computer being used by Busby.
Busby, of Richmond, California, made two statements to law enforcement officers shortly after the April 20, 2010 incident, ultimately admitting that he did download child pornography to two of his work computers, authorities said.
Officials said Busby told them that he would store the child pornography for a period of time and then delete the images.
At trial, Busby’s defense claimed that he accidentally downloaded the child pornography onto his computers while trying to access legal child modeling sites
In September, Busby, a sex offender from a prior conviction, was found guilty of possessing and accessing with intent to view child pornography, officials said.
