For Elizabeth's dad, Drew Collins, the likelihood his daughter's death is linked to
the Delphi case is not totally out of the realm of possibility, though he believes there's only a "very small chance" it could be.
However, what has given him a renewed cause for optimism in his quest to get justice for his daughter was a bombshell announcement made by police in Indiana last week that an
arrest had been made in connection with
Abby and Libby's deaths.
Investigators are still exploring whether others may have been involved [in Delphi murders].
Drew said the potential breakthrough has "
definitely" given him confidence that the culprit behind the murders of Elizabeth and Lyric will one day be unmasked.
"That guy [Richard Allen] wasn't even on anybody's radar, which just shows you these things can take time," said Drew, 51.
"We have a lot of good detectives working on this case and a lot of other dedicated people, and they aren't going to quit until we find who did this."
RENEWED CONFIDENCE
"It could take 10 years, it could take 20 years, it could take longer ... but we're going to find who did this, it's just a matter of when. We're going to expose that person, their whole family is going to know what they did, and everyone will know what they did to those two beautiful little girls."
