Out of all the unsolved serial murder cases I've looked into, this is the one that I am the most confident I know who the perp is. I am convinced that Joseph Blea is the West Mesa killer. Let's look at some facts here:
-Blea is a violent serial rapist who had exhibited predatory behavior since at least the 1980s.
-He may have started killing as early as 1985. DNA recovered from the clothing of Jennifer Shirm, a prostitute who was found dumped on a curb, was matched to Blea in 2009.
-Six years before the disappearances began, a woman walking along Central Ave identified Blea as the individual who called her over to his vehicle and proceeded to expose himself. Police later found rope and electrical tape in the passenger seat of his vehicle.
-Police did surveillance on Blea, and observed him stalking prostitutes for four consecutive days. They watched as he "slowed and circled the block in areas where prostitutes were working. He did not approach any prostitutes but appeared to be closely watching them."
-APD detectives talked to at least 20 prostitutes who recognized Blea, one which reported that he once brought her to his house and attempted to tie her up, though she didn't let him.
-His wife reported finding women's underwear and jewelry in the house that did not belong to her or their daughter, and that the daughter once reportedly found a stash of women's underwear hidden in the shed. As of February 2016, police would not comment on whether any of these items could be linked to any of the victims on the grounds of them being part of an "ongoing criminal investigation".
-Some of the victims families noticed that jewelry was missing.
-Blea's former cellmate was interviewed and stated that Blea appeared to have an interest in the West Mesa case, and that while he never admitted to being directly involved, he said that he knew and had paid for sex with some of the victims. He also reportedly referred to the victims as "trashy" when discussing the case, and even admitted to hitting one, claiming that she tried to steal his money.
-His wife has said that Blea would often express his apparent hatred for prostitutes, calling them *advertiser censored* and *advertiser censored*.
-Both of his former wives also stated that Blea would frequently leave the house late at night to dump landscaping debris out on the West Mesa and would sometimes later return with women's clothing and jewelry.
-The burial site was close to the area where Blea disposed of his landscaping debris.
-A piece of landscaping debris; a tree tag for a Spearmint Juniper, was found buried 8 feet below the surface in the grave of one of the victims. I strongly suspect that this tag got stuck to the victim's body while in Blea's vehicle.
-The tag was linked to a specific wholesale nursery in Vacaville, CA that sold to retail landscaping businesses in Albuquerque, one of which identified Blea as a regular customer.
The fact that a piece of landscaping debris was found in the grave of one of the victims, and that Blea was a landscaper with a history of sexual violence, predatory behavior, and frequenting of prostitutes, and who was known to dump his landscaping debris near the burial site is just way too much to be a coincidence. I have a feeling that police are fairly confident that Blea is their man, but don't have quite enough to charge at this point. In any case, he's going to die in prison for being a serial rapist anyway.
