Three of the children had been fatally poisoned, while 10-year-old Gavin had been stabbed, just days before they were due to stay with their father, Brady Harmon, in Utah for the summer. Authorities shared text messages that show Myers and Steadman “communicating and coordinating” the murders. That was the same day I was told the kids had a stomach bug and was asked to postpone my scheduled FaceTime call.” “Ok I will talk to the kiddos about the stuff they would like to do over the summer,” Myers replied, as if nothing was wrong. On 10th June, the day that the children are believed to have been killed, the mother claimed the children had a stomach bug.
