I believe finding a DNA match this way would allow for probable cause for a search warrant, which can include a more properly administered DNA test (cheek swab) that would be admissible in court. This is why I am not convinced LE has DNA for this crime (perhaps a tainted or partial sample) and why they are so adamantly appealing to the public for that "one tip" they need to bring this case to justice. I don't think the "one tip' is referring to a name, I think they are looking for something to doubt an alibi, or something that would hold up in court to isolate the suspect from a related pair, etc.
If they got a warrant for something based on something else that was illegal, the fruits of the poisonous tree doctrine would render it inadmisabble. Undoubtedly, they'd try to get a second sample upon arrest, regardless of admissibility.
I look at it differently. Perhaps they ARE doing all these things you have listed and HAVE BEEN for some time but are still looking for more evidence/info from locals to tie a few things together.
The 4/22 PC seemed very locally directed, to me. I've seen pics of my POI there. Maybe the 100 handouts were not all the same and who knows, he rec'd one with different wording or the image was in some way altered to get a response from him? They wanted him to sign in to the PC to get a handwriting sample, fresh DNA, prints?
IDK, just don't get why you insist LE have nothing. What do you know about the investigation? Are you a local there?
... I've already talked, and been banned, for condemning folks and their "POI's", so I won't rehash that. I'll wait for something new to provoke censure.
Law enforcement dedicated resources to publically solicited tips when they announced a new sketch and released more audio, hoping to provoke a new lead
from the public. Simply put, this is how they determined their resources would be best utilized - by responding and investigating thousands of vague tips based on a
second sketch and some additional audio. This is not an action law enforcement would take if they had literally any other option.
Think about it. When a murder happens, followed very closely with an arrest, are the police actively soliciting general tips from the public, or are they focusing that investigation on a specific person once that person is identified?

Stop. Believing. What. You. See. On. TV.
>IDK, just don't get why you insist LE have nothing. What do you know about the investigation? Are you a local there?
I do not believe they have anything because both their actions and inactions are those of an agency involved in an investigation with nothing, desperately wanting and hoping for something. I have as much personal knowledge of the investigation as you, which is nothing.
I am not a local, though my former mother in law lives in Lafayette, and my daughter visits frequently. None of this is relevant to the case. Though, this may play some role in my interest in the case. My ex-wife and her mother have no knowledge, intimately or otherwise, of the case.
