On Sunday, July 15th, Watts spends 23 minutes on the line with Vivint, his home security company. It’s likely this was prompted by Shan’ann finally FLIPPING OUT over the dodgy garage sensor. [Watts’ call to Vivint was prompted by a 5 minute call from Shan’ann about an hour earlier].
For the remainder of the day Watts seemed to be doing chores in the basement, possibly at Shan’ann’s behest. Remember she could not reach him the day before while he was out at the museum and canoodling with Kessinger. Watts took several photos of the inside of the basement and presumably sent them to Shan’ann to prove that he was done his chores.
We can only speculate what happened during Watts’ 23-minute conversation with Vivint. Vivint may have described the ins and outs of the technology, and how to work around issues. This insight may have come in useful a month later. Whatever Watts’ learned, the garage sensor remained busted when the cops arrived in mid-August.
In terms of the taking photos as “evidence” or as an alibi for chores, this seemed to be part of a habit in the Watts household. Just prior to murder of the children a month later, Shan’ann also asked Watts to send her pictures of the children in bed. He couldn’t on that occasion, because they were already dead. He resent pictures of the children from earlier in the day instead.
