Mike, can you confirm you still say you have itemised billing from the time of the murders that shows a call made from WHF to Jeremy?
I wasn't aware that a panic alarm had any tracking capabilities. I believe that there would need to be another piece of software.
Don't think I've ever read that a panic alarm was actually installed at the time of the murders, if it was it would make sense that SOMEONE would have used it during the slayings.
