Rosser is infamous for being on the Federal Bureau of Investigation's "Ten Most Wanted Fugitives" list[2] for his involvement in the production and distribution of child pornography in 2000.

Rosser lived in Bloomington, Indiana until the early 1990s, when he moved to Thailand and began giving piano lessons to students who would become among his victims.

[2] He was sentenced to over 16 years after an investigation revealed he had recorded himself sexually assaulting a young girl, and then traded it to an Indiana man for different pornographic material.

The fellow passenger called Billings police to the bus station, and when they arrived, Rosser admitted to looking at the images of young girls engaging in sexually explicit conduct.

Rosser additionally admitted to violating his probation conditions and fleeing federal supervision in Washington state, court documents say.

Rosser pleaded guilty to accessing the internet with intent to view child pornography after signing a plea agreement with prosecutors in October 2018.
