I've searched all over and can't find what I'm looking for--does anybody else remember an article that had a quote fro one of the Rexburg area LE saying them that Arizona LE contacted the Idaho people about looking into Tammy's death? Or am I being more random and scrambled than usual?
You are not random or scrambled at all, Carbuff!

Copying a few sources from the media thread (BBM):
EastIdahoNews.com asked Humphries if Chad Daybell was acting unusual or suspicious when deputies were at the home.
“To my knowledge, he was responding like anybody would whose spouse had just passed away. That’s why the deputies didn’t suspect anything suspicious,” Humphries said.
A few days later, Humphries said his office was alerted by detectives in Arizona about the other deaths. Tammy’s body was exhumed from the Springville Evergreen Cemetary and an autopsy was performed. Investigators are waiting for autopsy lab results, which could take a few more weeks.
One question that has been raised is whether Tammy Daybell had a large life insurance policy. Humphries said he could not comment on that issue but confirmed it is being investigated.
“There is some information along those lines that I’m not at liberty to speak about right now,” he said.

Fremont Sheriff's Department is heading up the investigation into Tammy Daybell's death after she died at her home in Salem, Idaho, 15 minutes — and across the county line — from the apartment in Rexburg where the children were last known to be living.
[...]
Humphries revealed that police in Arizona alerted his department that things may not be as they seemed. In his 12 years as sheriff, he said he had never had any contact with Chad Daybell.
'Then about 10 days prior to her death we got a call that a guy in a mask was firing paintballs at their house. By the time we responded of course there was no one there. The feeling was it was all a prank.'
