Two questions for you.
1. What was the motive? Why would anyone want to kill a physical fitness instructor? A killer has got to have a motive.
2. Why would he go though all the trouble of burglarizing the church, and braking every door in the place for half an hour, just to kill one person, who he could have killed outside?
In my opinion unless you can come up with good answers to those questions, the hit man theory doesn’t hold much water. That’s just not the way hit men work. A professional hit man would have waited for her outside and shot her in the head as soon as she got out of her car. Then he might have taken her purse to make it look like a robbery, or he could have shot her out on the road, and made it look like a road rage incident. But for a hit man to spend half an hour busting up a church, while waiting for her to arrive, so he could bludgeon her to death with burglary tools, would be a waste of the hit man’s time, and a very amateur way for a hit man to kill someone.
To answer some of your questions.
1. He din’t make a pile, because he was looking for money and valuables, which he obviously hadn’t found yet.
2. I don’t believe there is any evidence that he had any “real" weapons or LE gear. He had burglary tools, which he used as a murder weapon, and novelty SWAT gear .
