In texas, yes, when robbing a house, there could be a safe or gunsafe inside. It is possible the robbers brought a handtruck for that reason. Personally, its not something i would bring to a robbery. Get in, jewelry,computers, game system,cash, art, something you can snatch and run,and get out. Anything that needs a handtruck, too risky and too time consuming. Imagine a robber nervously ransacking a house, stopping and saying, hey, here's a pinball machine, get the handtruck.
I agree with beezleboob and I said it before, the whole story stinks.
Is it possible, yes, but not likely. Robbers, who just happen to have a handtruck, happen to rob a house where the person is in the process of moving. They take one pinball machine , a bed, and some fence. A 20,000 dollar pinball machine just happens to be all prepped and ready to go.
As for the craigslist ads. sounds like they wanted to see how many emails they could get at offering it at $5000. Then they upped the joke to $11000. When emails slowed down, they re-baited the hook at $5000. Its too bizarro to be real.
stinks stinks stinks all around.
