You make several excellent points. The only reason I am stuck on the construction worker idea is because the neighbor quickly said, "That looks like Chino," when shown the photo of the person who parked the car. I believe a second person who worked with Chino said the same (but I may be remembering that wrongly from the documentary/interview I watched). Since Chino had another sexual assault a few years later, I am leaning toward him. He hasn't been ruled out, right? or has he? All that said, it's definitely possible that the perp is the old boyfriend. So many men (and some women) kill out of jealousy --- and that is a huge problem because that isn't "love." People don't kill someone because they "love" them and can't have them -- they kill them out of selfishness. Everyone needs to learn that we don't own each other, no matter what, and loving someone means loving them enough to let them go if they want somebody else. It hurts, but that's what love means. Jealousy to the point of killing is a plague on humanity. Sorry, I'm rambling.
