This isn't going to sit well with some folks and isn't meant to send this to the cave.
There are a variety of ways a law enforcement agency can issue a warrant. Just having a warrant doesn't necessarily equate to being arrested wherever you are.
Basically the agency that issues a warrant has the option of flagging it so that if the suspect is found by any department in the US they are taken into custody for the outstanding warrant. If they issue the warrant like that the agency that put out the warrant is responsible for transporting and paying for the transport of the individual from wherever the heck they were arrested back to face the charges.
Many departments can't afford to pay to do that or to send an officer across the country to pick someone up. The result is they habe a warrant out for their arrest and the issuing agency may even know where they are, but cost prevents them from being arrested.
Not saying that's what happened here, but it wouldn't surprise me either.
But does it matter? TCU and Gary should have known about it. They claim they didn’t. That’s the issue.
