What evidence is there that the homeless man was in on it? The news doesn't say. Is it just the word of the couple? The two have have proven themselves to be liars & cheats and good at concocting stories? They could have just turned on the homeless guy, figuring if they were going down, they are taking the homeless guy down with them, since he's the one who turned them in, in the first place.
I'm not saying I think the homeless man is innocent. I always thought it was odd that a woman travels at night, alone, on I95 with no money or credit cards, no cellphone and no gas in her car. That is an assault waiting to happen as she is a sitting duck on a busy interstate. Any woman who regularly drive along I95 knows better. But, then a homeless guy saves her instead? I'd just like to know how the police figured out the homeless guy was in on it all along.
