Oct 1 is the only time Lori visits the unit alone; She is driving a blue Nissan Rogue. She is seen removing a heavy tote from her car and placing it into the unit after she signs the contract. Later CCTV shows Lori and/or a man associated with her visiting the unit nine times in October and once in November (East Idaho News, Dateline).
2 Oct 2019, abt 9:14 am – BB, husband of Lori’s niece Melani, is shot at in the driveway of his Gilbert, AZ home; A bullet narrowly misses BB and shatters the driver’s side window of his Tesla. At first BB thought the shooter was using a paintball gun, due to the sound it made, but when he examines his car he sees a bullet hole and realizes it was a real gun with a silencer. The shooter is driving a vehicle matching the description of Tylee’s Jeep. BB calls 911. “Did you see the guy that, that actually—” The dispatcher begins to ask. “I didn’t see who it was,” BB answers. Much of the call is redacted. It’s unclear what he was telling the dispatcher but in later interviews, we learn BB suspects it was Alex driving. BB knew CV well, knew all about AC shooting CV in July and recognized the Jeep. After GPD arrive and take BB’s statement, a police report is filed, and an attempted murder investigation begins. The Jeep was caught on CCTV and was later confirmed to be registered to the late Charles Vallow. After the shooting attempt on his life, BB takes his 4 children and goes into hiding with them (Family interview on GH; Fox News & Arizona Republic, Dateline).
