NO. When she gave him the "console" as a GIFT she
lost all property rights in the console. It's his!
Additionally, he can sue her for DEFAMATION and
MALCIOUS PROSECUTION if she tries to file
"criminal" charges. Tell her to grow up . . . and
SHOW HER a copy of this email.

It boils down to a fact question. Was it a gift or not? It's a classic "he said- she said" situation. It's up to the police to investigate. If she gave him a card with the gift, it'd be too handy. Ordinarily, I'd tell him not to talk to the police. But they need to know it was a gift. He needs to talk to a criminal defense lawyer now to head off any charges.
I am not intending this to be legal advice, because I don't know the particulars of your situation. Call me if you would like to discuss this or other isues.
