My comment on Dna testing was meant to say that they prolly have that data NOW.. (not necessarily what led to the knowledge of Sarah's location).
I am sure he left other evidence, OR there was a tip.
As for forensic testing, there are much quicker tests available than what we all think of as "DNA testing"- there is blood typing (can have within an hour), male/female, etc. I was really not saying that the blood or beer can forensics tests led them to MH, but rather, they could have, pretty quickly, RULED OUT (vs ruled in) whose blood was in the house depending on personal physical characteristics.
As for actual DNA testing, I said 24-72hrs. Technically, finding the beer cans on Thurs eve could have given a match to MH by SAT. But as others have said, the knowledge that only Sarah was known to be there... well, who knows. There may have been a tip, or there may be "other" tissue they recovered besides blood, indicating lethal damage to the others. LE is not gonna compromise this case, so you will hear VERY little on what they found. Unless there is an unintended press leak, I think we will all have to wait until the trial is done. The last thing anyone wants is a MISTRIAL, or to have it moved out of the area. I can guarantee you, the DA is very active right now in what goes out to the public, and EVEN the family. The families are told very little, unfortunately.
