Why are these still unsolved?

Limitations in investigative technology at the time, loss of evidence, or simply the absence of any witnesses are the common threads cited for why these cases still lack a definitive conclusion decades later.

Could new evidence ever solve these?

Yes β€” as new scientific techniques like DNA analysis continue to advance, long-cold cases are sometimes solved after all, so the possibility is far from zero.
