The Australian grandfather who's believed to have gunned down his wife, daughter and grandchildren "didn't snap," according to the grieving father of the slain kids. He was "thinking this through for a long time," Aaron Cockman said, per BBC. Peter Miles, 61, reportedly killed six people in rural Western Australia before taking his own life. Despite the incredible blow, Cockman, who was estranged from Miles' daughter at the time of her death, told reporters he was grieving the loss of his children but still has love for Miles. "I still love who Peter was," he said. "If it wasn't for him I wouldn't have Katrina, I wouldn't have any kids. So it's not some random guy off the street who's taken them away from me, he gave them to me and now he's taken them away."
Police arrived to the family's farm Friday to find Peter Miles and his wife, 58-year-old Cynda, dead. Katrina, 35; Taye, 13; Rylan, 12; Ayre, 10; and Kayden, 8, were all found dead nearby. Cockman's emotional press conference in the town of Margaret River on Sunday came after his family's tragic end made international headlines, in part because of Australia's oft trumpeted gun-control laws. This is the deadliest mass shooting in Australia since a lone gunman massacred 35 people in Tasmania 22 years ago, causing the country to introduce much tougher gun laws, the Australian Broadcasting Corporation reports.
