I have tried to think of things as well -
His route - but LE believes he’s familiar with the Delphi area and trails so there’s nothing that would stand out about that as unique.
Cause of death - Surely anyone who knows anybody associated with Delphi, who exhibits behaviour indicating they’re capable of killing another human is sufficient? How the girls were murdered is secondary. It’s not as if someone would be sitting back “oh I know he only kills people by stabbing” awaiting an officially announced COD.
Vehicle - This one has reached a dead end a few times in prior cases. Unless LE are absolutely certain the suspect is known to be associated with a specific vehicle it can just as easily lead an investigation in an entirely wrong direction. Besides, LE has access to vehicle registry information without the need for public assistance.
Any items found near or at the crime scene - Was anything found that would be unequivocally associated to the killer, we don’t know.
Audio/video - LE claims that’s it, as far as the killer’s audio and video. As for the girls chatting, if LE, other specialists and professionals and the family are unable to identify any ‘clues’ from the audio, there’s no point in LE releasing to the public what would obviously cause needless heartbreak and anguish to their loved ones.
Shoes - If a footprint was discovered in mud, was it clear enough to determine shoe size, make and style of footwear almost 24 hours later and can LE rule out nobody else created that footprint? We don’t know the answer to that either.
I can’t think of anything else…..?
I’ve been trying to think along similar lines - if BJC is the killer, what could LE do to look for evidence?
Obvs first call is to search any premises or possessions under his control.... but there’s probably very little of this since he’s been homeless, evicted, imprisoned etc in the years since.
I wonder if, MOO speculation, when BJC was first IDed LE hoped to find something among whatever he’d been able to maintain (EG maybe some boxes of stuff stored at his fathers house even after eviction). If there was something to search, I can imagine lots of optimism as they got started. But maybe there wasn’t much & it turned up nothing .... so the optimism faded as time dragged on. MOO
If this is right - if there was far less to search than w a normal person since he hasn’t maintained a home etc - where else can LE look for evidence??
-> as you described, contemporaneous stuff from crime scene - EG if a nearby discarded cig butt had BJC dna (tho if so that presumably would’ve led them to him much sooner), or as you said shoe prints matching his, etc, anything saved from 2/17 to eventually help ID perp
-> interviewing any alibi witness BJC might provide & anyone else who was in contact w him at the time .... but chances are IMO this is a very short list. Would not be surprised if not a soul on earth knew what this drunken wreck jailbird violent felon was up to at that point in time. Assuming MOO he was estranged from his brother & father / any other fam & any poor woman who might’ve been nominally his wife / GF .... this route could’ve yielded nothing at all.
-> any online records he might’ve left - posts showing a location, self-implicating comments or msgs on SM, anonymous comments that could be tied back to an IP address he’d used - this has good potential for at least circumstantial findings, but could also yield nothing
-> what else ????
Any ideas?
Assuming the loser will not provide a confession (tho he still might as he works his way thru crim just system ... does IN have death penalty to threaten him with?) - what else might LE possibly do to tie him to this 4+ yo crime?
Hopefully some of yall have more knowledge here & can make some good suggestions ....
I still think BJC is the perp IMO & the prob is that evidence is elusive .... if I imagine decades into the future, this case never solved & has become history & someone asks why LE never found perp, I imagine my answer being (a not-uncommon answer unfortunately) there was a clear candidate but they just couldn’t ever pin it on him .... which is to say, BJC will remain my choice perp JMO unless & until a better one is IDed.
