Thanks for the clarification...
I found it strange he was being called a rapist, but was charged with sexually assault...when by code he could have been charged with rape...
Now I know the rest of the story...
The two rape charges were dropped on the first day of trial. There was insufficient evidence to support the two rape charges.
He was convicted on the other three charges.
See referenced police report for the charges filed.
