'I'm a monster': Michele Anderson heard on tape confessing to killing 6 of her family members Feb 10th 2016 2:14PM SEATTLE (KCPQ) -- The woman accused of killing six members of her family in Carnation could be heard calling herself a monster in a taped confession to police. The prosecution played Michele Anderson's confession to jurors at her murder trial Tuesday. : The slayings took place on Christmas Eve 2007. With detectives and reporters swarming the area around her parents' home after the killings, detectives say, Anderson never once asked about the well-being of her family after she returned to the crime scene. Police became suspicious, eventually getting a chilling confession to the murders. Anderson told detectives she and her boyfriend, Joseph McEnroe, were on their way to Vegas on the night six of her family members were murdered. But halfway into her two-hour interview with detectives, Anderson broke down and admitted to killing her parents, Wayne and Judy Anderson, her brother Scott, sister-in-law Erica and their two children, 5-year-old Olivia and 3-year-old Nathan. "As soon as I shot the gun, I felt so bad, like what the hell have I done? I'm a monster, I turned into a monster. I told Joe to lie to cover up what I did," Anderson said in the taped confession. Brewing with anger over money she said was owed her, Anderson says she planned out the Christmas Eve murders for two weeks. "My brother owes me a lot of money and he refused to pay any back, he knows we`ve been struggling," Anderson said. Anderson says they shot her parents first, hiding their bodies in a backyard shed. Then the couple waited for her brother's family to show up. "He was trying to rip the gun out of my hand while I was shooting him; I shot four shots into Scott with the revolver and two into Erica. I ran out of bullets; that`s why he (McEnroe) shot the kids," Anderson said. She says she ordered McEnroe to shoot her niece and nephew. In her desperate attempt to save her kids, Erica tried to call 911. "She lunged over the couch even though she, she had been shot twice. I don't know how she did that," Anderson said. They grabbed the phone from Erica, turning the gun on the kids. Anderson says they killed the kids to get rid of witnesses but also because she wanted to spare them from living with the horror they witnessed. "They were clinging to their mom screaming. I just thought if they saw their parents dead, that they would be scarred for life," Anderson said. Anderson showed little emotion in court while listening to her own confession. McEnroe was convicted of the murders last year and was sentenced to life in prison.
