I agree the calls made around 2014/15 are important, because that was around the time when Mary disappeared (potentially 9 years ago, not 2009).Except some of the calls were made right around and possibly after Mary was deceased and as it's been stated, no one has officially seen Mary since approx 2009. Some of those calls were made in 2014 and 2015. So, who were the calls made for/about? Why didn't anyone speak to Mary, who is the homeowner of the residence that the calls were in reference? I feel that something would have been revealed much sooner than now if that had been done. JMO.
My point, I suppose, was more that a call/complaint being made to police is not the same as an investigation leading to charges, so the complaint is not 'proof' or evidence of anything, eg elder abuse in 2019.
