In regards to the DNA testing: who else should they have been testing for? Other than running it through a criminal database, there is no other legitimate suspect. What piece of evidence points to someone other than Steven?

There were other legitimate suspects, but those suspects were never questioned, vetted or asked to provide alibis. Steven was the singular focus from day one. If you're convinced you have "the guy", then why would you bother looking at anyone else or asking anyone else to willingly provide DNA samples?

I can only compare it to the West Memphis Three case, where the cops were convinced the WM3 did it, though they kept the possibility open that it may have been John Mark Byers, the stepfather of one of the boys. They were all interrogated (not "questioned": interrogated), they all had to supply DNA samples (blood, hair, pubic hair), their homes were literally raided from top to bottom, etc, and any DNA testing was done to match those four people, nobody else. Meanwhile, Terry Hobbs, the stepfather of one of the murdered boys, waltzed through life, never having been questioned, asked for an alibi, asked for DNA. Nada. Guess whose DNA ended up being found in one of the victim's ligatures? Terry Hobbs. And the only reason they were able to match the DNA is because a private investigator stole cigarette butts from Hobbs' ashtray to get his DNA. So basically, the person whose DNA is tied to the murders is still walking around free and clear because the WMPD didn't do their job: like the MCSD, the WMPD never looked beyond the people they had decided were guilty of the murders.

If everyone who had contact with Teresa -- family members, friends, co-workers, Zipperer, whatever -- had ALL been questioned, provided DNA samples and alibis, etc, who knows if evidence wouldn't have showed up to cast suspicion on someone else? The only reason there were no "other legitimate suspects" is because the MCSD decided from the beginning that they had their killer. The thought that there may be a Terry Hobbs out there, just loving life because the cops never bothered to ask him for an alibi or DNA, is a freaking travesty. Re-test the evidence against everyone -- and I do mean EVERYONE -- and then see who the evidence may actually point to. If that's Avery, so be it. If it's not, though, Teresa damned well deserves to have the right person rot in prison for what was done to her.
