Referring to the previous post, I cannot find any photos of DMN's tattoos, but CV's do not appear to match any of the UID's, plus at five feet seven and 130 to 140 pounds, she would be too thin to match the UID's "large build" description:

This article raises some interesting points:

The two pieces found December 20 were on a subterranean staging platform that is part of an "interceptor," which is drained before the work crews were needed:
I'm not about to cast suspicion on the workers themselves, but since TobyWong* above suggested someone might know the sewer cleaning/maintenance schedule, it would be worth it to know the condition of the December 20 pieces. Did they show any evidence of being submerged in the sewage for long? At all? The map shows the discovery site to be in a populated area so it's doubtful someone could have slipped into the sewer to plant the pieces as the platform was draining, but maybe they were dropped into a storm drain nearby and got caught on the platform as the last of the water flowed over it?
