Any detectives out there?

I respect everyone's opinions, however, I would never pick up a pennysaver to hire a handyman and invite this strange man into my home, like I said before, if I wanted to be nice to him, I'd buy him a meal, not give him a key to my home. If I needed handywork done, I would find a family member or friend to do it or help. Apparently, he was hired to HELP Mr Smart, so it's not like they got him to do the whole job. Mr Smart must of had a clue as to what he was doing and some knowledge of handywork......
Sorry, the family had bad judgement and put their kids at risk, that's why she was taken.
