Wow, this IS a tough one. I just finished reading through most of the posts related to this case. I thought this didn't look like a professional hit for a couple of reasons. First, witnesses said they saw the car moving slowly down the block, the driver looking at house numbers like he didn't know where he was going. As Mr TT said, if it were a professional hit this guy would know exactly where the house was days in advance. Second, if it was a professional hit, either the housekeeper OR Thomas was targeted, right? I find it unlikely the woman and boy were connected together in some seedy business and that they were BOTH targets - my point being: if a professional hit, and the housekeeper was targeted, the hit man would NOT have gone for her while she was at the private home of her employers which is located on a quiet, wealthy residential street, because again, whoever was behind the hit would have thoroughly checked the situation and known that there was a chance her employers' kid would be around, if not the employers' themselves, not to mention neighbors. Ultimately, if a professional hit, and the housekeeper was targeted, it seems unlikely they would go for her in the Hunters' home (on a day she wasn't even supposed to be there, at that.) Based on this point, however, I guess it would make more sense then, if it were a professional job, that Thomas was the target. If the housekeeper wasn't supposed to be there that day, the hit man very well may have thought, after surveillance of Thomas's and his family's schedules, that he'd find the boy alone that day. However, I have a really hard time believing an 11-year old boy, especially one seemingly as normal and well-adjusted as Thomas appears to be (not a truant, or into drugs, or burglaries, or any other of those juvenile crimes), would be the target of a professional hit.
Unless, of course, as some of you seem to think, the boy had inside information that may potentially damage important, powerful people. Meaning what? Sexual abuse which may or may not be linked to past events in Omaha (of which I do believe occurred, by the way)? Could Thomas have witnessed a crime? Was he involved with shady people on-line, through video games or something else? I suppose all of these are possibilities. Can anyone think of any other reason a boy like Thomas would potentially be a target of a hired killer?
Another thing I read is that they were stabbed to death in the necks and heads, indisputably a horrific way to die. Isn't it known in forensic circles that generally speaking, a stabbing speaks that it is a "personal" crime, or something along those lines? That in most stabbings, the perpetrator is someone the victim knew, and was likely close to? I guess it takes a lot of rage/passion to stab someone, and it would be difficult for a stranger to have those feelings for another stranger. More likely a stranger, if he had to use a knife, would slit the victim's throat, perhaps, but stabbing just seems really personal to me. And I've never heard of a professional hit man stabbing his "targets" - too messy, too large a chance of being cut himself and leaving blood/evidence behind, takes too long/allows for the possibility of the victim screaming and attracting attention to the scene, etc. Multiply these risks by two (there being two victims) and it makes a professional hit even less likely in this scenario -- unless of course, it was a really stupid, inexperienced hit man, in which case, it wasn't really a professional hit, but merely a murder for hire done by really sloppy people.
Then again, whoever he/they are, they haven't been caught yet, so who knows? This case really is sending my mind in circles. I am quite sure, however, that Thomas was the intended victim, either as revenge on his parents or for his own reasons, and that the housekeeper was in the wrong place at the wrong time. If the housekeeper was the target by a family member, local drug dealers, etc., with the reward money being offered, I think this one would have been solved long ago. Someone would have talked. That someone hasn't makes me think a more intriguing person/people are involved, and that that person/people has connections to the Hunters, be it Thomas, his family, or both.
