I somehow missed that.
Since my understanding is that Isabella Janke is a student at Texas Tech University, and has never actually met Chris, Isabella Janke presumably committed the thefts, extortion, and computer crimes (in the form of unauthorized access to electronic systems to whit a bank account) using the internet. This would create federal jurisdiction as more than one state is involved, which means Isabella Janke has committed more federal crimes.
The Greene County investigators, however, are unlikely to take notice of or even care about the federal crimes of Isabella Janke. Their job is to deal with finding evidence to prove Chris guilty of the crimes they are charging him with.
Chris certainly could make a report to the appropriate Federal law enforcement agency regarding the federal crimes Isabella Janke committed against him. But the great thing about reporting crime is that anybody can do it.
I encourage any good American citizen reading this who believes they have knowledge of federal crimes committed by Isabella Janke, a Texas Tech Student, to do their patriotic duty by reporting what they know about the federal crimes of Isabella Janke to the federal law enforcement in or closest to Lubbock Texas, where Texas Tech University is. This will probably be an FBI field office. I suggest this location because it is my understanding that Isabella Janke committed her federal crimes while a student at Texas Tech University and also a member of the Texas Tech University Chess Club.
