WA WA - Spanaway, Three human skulls, 2002-2004 - connected?

I'm not sure if any of these have been posted before or not. I was browsing through cases on NamUs today and wanted to bring a few to your attention. Maybe it's just a coincidence, but I found 3 cases where human skulls were found in WA. One in 2002, a second in 2003, and the last in 2004. The first two were found less than 3 miles apart in Spanaway WA. The Third one was found about 20 minutes away in Roy WA. Anyone else think there could be some kind of connection?

I'm thinking Gary Ridgeway or Ted Bundy, both of whom operated in Washington state. NamUs says that the remains are up to 5 years old, but I wonder if there really is a way of knowing beyond a few years.

Of course if they were that recent, that would rule-out Bundy or Ridgeway.

Maybe only the third case is connected with serial killer Gary Ridgeway for the times (estimated postmortem) is most possible.

IIRC around the time these remains were found, Law Enforcement was acknowledging a serial killer in Washington State but not saying more than that. (I lived in nearby Montana at the time so a Spokane TV station was running a story about the elusive serial killer.)

Just my contribution. Could be a couple of scenarios going on here.
