LE took dna samples from anyone who was willing to give it. They took them from family, friends, probably even neighbors, anyone who said they had access to that house. LE has said that they have evidence taken from the home, but will not say what that evidence is. They also said at one point that the samples didn't come out right, so they had to collect them again. Imo, they were looking for the owner of dna that had not yet been identified that was found in the home that night. I think this is a possbility, yet they don't let Misty off the hook, so imo, they must think she invited them in. jmoooc.
