The family held a press conference and key new items of note were that Tina was working for a neighbor named Tom who asked her to deliver an "item" for him and that item was found in her purse in her bedroom (item later ID as a flash drive by local news). The errand was supposed to take Tina and Mike to Mesa. She also missed a doctor appt. on Monday, so it appears she took off from her primary job (Tom's jobs were extra work she would pick up as he needed), the brother-in-law also mentioned a man we are calling "JV" and said that he was a friend of his dad's and that JV was interested in Mike's flying.
Shortly after the press conference, a search warrant is issued for an address about a mile from the family compound. The address is sleuthed to "JV," but it may not be his primary address. The house looks somewhat abandoned, even though Animal Control removed a large Rottweiler. The Crime Scene Unit was dispatched and began digging under some tarps very close to the house. They reposition a tent several times presumably to keep the new choppers from filming. They stop digging in the deep hole and start taking photos. The choppers fly away (not sure if it is a refuel or if the they were ordered away). All digging stops and the LE is talking on the other side of the house. Speculation is they are waiting for coroner's van before proceeding.
Meanwhile, 3 farm workers were arrested and a man bystanders say is "JV" were all taken into custody. No one has been named a suspect yet, so we cannot use JV's name. No motive, but it appears someone told them where to dig because they were measuring from the house and began digging. I don't know how the family can stand watching this unfold. It's been nerve-wrecking.
