Trailer Park Tales-Book #2

I've been working on the second installment of Trailer Park Tales, which will follow Once Upon a Trailer Park sometime in the next few months. The same four couples you met in Book #1 will investigate a cold case, finding a man sought by police for two fifty-year-old murders. The word is he lives at B-Bird, but he's changed his identity, so the cops ask Ron & Julie to do some digging. They involve the other couples, because really, how much danger can there be with a crime from 1967?
The book is almost together, which means I'll soon be sending it out to beta readers, editors, book reviewers, etc.
What I don't have is a title, and that's where you can help.
I'd planned to follow Once in the first title with Twice in the second. But when readers search for mysteries, they use keywords like murder, crime, suspects, death, kill, etc. I can't come up with a way to do both and come up with a catchy title.
I've been spitballing ideas all morning, hoping one will stick, but I'm stuck. Below is a (very rudimentary) mock-up of what I think the cover's going to look like, and a list of possible titles I came up with. Any help, either votes for one of mine or ideas of your own, will be greatly appreciated.
