Do you think his name was even Jackson Rippner?
He says he never lies, but he does about calling off his assassin. Also, it's just way too convenient that he would have the same initials as her dad, thereby making it easy to pass the wallet off as his own. I also don't think that he'd tell Lisa his real name. In theory she would have survived the ordeal and would've obviously told the police about him. Why would he leave a paper trail straight to his real identity? I'm thinking fake ID, fake boarding pass, etc for him.
