I was just going to comment on this as I recently rewatched the Cold Justice segment that concluded her killer is her former boyfriend, RS, and was so hoping he would be indicted because I've always thought he was the perpretator but it doesn't look the case has gone anywhere. The Cold Justice episode is about a year old now and there has been no indictment.
I think this case is a win win really. I do wish the detectives would have used the opportunity of flying out to meet RS at his nice home in Hawaii more diligently. He was finally talking about the case but they only asked him a couple of fairly insignificant questions and he backed off. It was waisted opportunity to get some kind of admission out of him. They could have asked, "Is it true you choked her during sex?", "Were you following Jennifer in a car the night she was murder?", "Did you love her?", etc., but I'm surprised RS even showed on camera or at least that he didn't shut the interview down right away, but it's really sad to know he's living the dream in Hawaii, far away from the place he killed Jennifer.
He was probably seething that night, after seeing Jennifer with Travis, and, later that night, knocked on her door. Jennifer probably only opened it slightly ajar before he gave her a sob story to get let in, and, Jennifer, while apprehensive, probably gave in until he told Jennifer he wanted to rekindle the relationship and that's what pushed the red button—when she rejected him.
Cold Justice mentioned her finger nails were broken but they never covered whether there were any scratches on RS or what skin cells were located under her fingernails that she used to defend herself in this brutal attack; the killer was in a rage and Jennifer fought so hard she broke a fingernail. What, if any, DNA was under her fingernails? This case should have been prosecuted—just compare it to other cases with the evidential equivalence or less.
I really do hope he faces justice.
