Pullman police arrested a WSU employee for child pornography charges on campus Friday morning.

The employee, Robert Marshall Long, 56, who works as a research technician in the Institute of Biological Chemistry on campus, was arrested in his office in Clark Hall, according to a Pullman Police Department news release.

Last August, Pullman police received a tip from the National Center for Missing and Exploited Children that a Pullman resident was uploading depictions of minors engaged in sexually explicit conduct to an internet storage account.

According to the release, Scott Kirk, a PPD Detective and Internet Crimes Against Children Investigator was assigned to the investigation and determined Long to be a suspect. With the assistance of other ICAC investigators and the Moscow Police Department, Kirk investigated Long, which led to several search warrants at Long’s home. The police seized his personal computer and found several images depicting minors engaged in sexually explicit conduct.

With the help of WSU Police, Long was booked into the Whitman County jail and charged with possession of and distribution of depictions of minors engaged in sexually explicit conduct. According to the release, both offenses are Class B felonies in Washington state, punishable by up to a decade in prison and $20,000 in fines.
