This is interesting, considering the sketch of the two guys. But they were definitely looking for him. He was targeted. I personally do not think business was enough of a reason for a person to do this to someone. Especially when they had no idea if his children or wife could have opened it. This had to be motivated by pure hatred. So much anger and hate that they did not care what happened as long as it hurt him. He had many affairs, some with married women. My money based on what I know about this case is that a husband did this.
