A Camas woman accused of trying to kill her live-in boyfriend with a samurai sword because she believed he was cheating on her pleaded guilty Wednesday to attempted first-degree domestic violence murder.The prosecution will recommend a 20-year prison sentence for Emily Javier, 31, while the defense is free to argue for a sentence below the standard range of 15 to 20 years.Javier will be sentenced March 11 in Clark County Superior Court, following what the attorneys anticipate will be a contested half-day hearing. Her defense attorney, Chris Ramsay, told the court he plans to call at least one expert to testify.On Wednesday, Javier admitted to taking substantial steps toward trying to kill her boyfriend, Alex Lovell, then 29.She previously told investigators she hatched a plan to kill Lovell, whom she had been dating for two years, and specifically bought the sword from a store in Vancouver Mall for that purpose. She hid his cellphone so he couldn’t call for help, attacked him in his sleep and then called 911 only after she believed he was dead, according to an affidavit of probable cause filed in the case.The affidavit states that she told officers, “I was trying to kill him for cheating. That was my purpose.”Lovell was found inside the couple’s bedroom with several life-threatening injuries.In an interview with The Columbian 1 1/2 weeks after the attack, Lovell said his index, middle and ring fingers on his left hand were “pretty much” cut off at the base, though doctors were able to reattach them. His right foot sustained a clean cut, and his left knee suffered a laceration that required a metal plate to repair some of the bone, he said. His right wrist was put in a cast. He suffered minor lacerations on his torso, a “decent cut” on the left side of his head, as well as bruising on his neck.
