No, the PCSO has led the multi-agency investigation from the beginning. The FBI has assisted.

Imo PCSO intentionally released the scene (after only 20-22 hours) - before the FBI could show up. In that sense, it was already a contaminated scene when the FBI got there. Can you take fingerprints on top of fingerprint dust? Collect DNA after however many local investigators have walked around, touched things, moved things?
How would the FBI know if a door was open or propped open? By who? Would PCSO investigators have left it that way? How would they know if the door cam was taken by the perps - or by the PCSO?
I believe Nanos harbors a grudge against the FBI from the past (this has been discussed earlier in thread), and intentionally closed them out of early involvement, thinking he might only need them for cell phone / GPS / digital analysis. Jmo
Nanos himself acknowledged in an interview that "officers believed they had released the crime scene prematurely". (BE)
To me it boggles the mind that PCSO investigators, upon seeing significant drops and aspirated blood on the front porch, a missing front door bell camera, and lantana on the ground under the camera location -could leave without taking the camera bracket, the door mat, and the lantana back to the lab for possible (additional or future) forensics testing.
And now some are raising questions re: the lack of experience by the lead detective?
It's not just BE's reporting re: Nanos and PCSO that is shining a light on the mistakes made by Nanos and his department. You don't have to look very hard online to find dozens and dozens of articles about Nanos' controversial past in LE and accusations of poor leadership, favoritism, retribution, and disciplinary history. You will also discover that this has been going on a long time.
Whether it was technically wrong for Nanos to attend an Arizona basketball game in the front rows just days into the investigation, it drew unnecessary negative attention to the investigation. In my opinion the decision to attend added fuel to the fire for those already questioning his judgement.
The Pima County Deputies Organization (PCDO) voted unanimously to express "no confidence" in Nanos and call for his resignation.
The Arizona sheriff leading the fruitless effort to find Savannah Guthrie’s missing mother received a unanimous “no confidence” vote from a large police union of his underlings, c…

I think Nanos' premature release of the crime scene harmed this case, and I think most observers agree (jmo). I have seen zero evidence to support that there has been any conspiracy on the part of the FBI to make Nanos and/or PCSO look bad.
