PULLMAN, Wash. – Pullman police arrested a man in his Washington State University office after getting a tip from the National Center for Missing and Exploited Children about a man uploading depictions of minors engaged in sexual conduct to the web.

Pullman PD said in a release they arrested Robert Marshall Long, 56, in his office at Clark Hall on Friday morning. Long, a Pullman resident, was a research technician at the College of Agricultural, Human, and Natural Resource Sciences (CAHNRS) according to the university.

Phil Weiler, vice president for marketing and communication at WSU, said they do not believe Long ever interacted with children on campus.

“He was a research technician so he wasn’t the kind of person who would have interaction with children on a routine basis,” Weiler said. “Not that we have a lot of children on campus, but there are from time to time kids around.”

Police booked Long at the Whitman County Jail on charges of possession of depictions of minors engaged in sexually explicit conduct first degree, and dealing of depictions of minors engaged in sexually explicit conduct. Both are felonies in Washington, punishable by up to 10 year imprisonment and/or $20,000 fine, according to Pullman PD.
