Wow. Just crazy. Sooo happy there is an arrest. How awful. I wonder if he was doing anything sketchy with company finances in his position - embezzling or faux accounting that she found out about and was going to report.
Or maybe he was just a stalker. How senseless. So sad for Carolyn and her family, just going about her day and minding her own business. And then for him to keep going to work every day where she had worked. Insane.
Police must have had their sights on him early on. Wonder what the confusing/conflicting timeline was - maybe something placing him at the scene/time. Sounds like they knew it was him and were just biding their time for evidence. And good for Carolyn for getting his dna under her fingernails, as sad as that is. She must have fought.
