Homicide victim Kori Fredericksen in 2011. Nearly four weeks of testimony ended Tuesday in Dennis Wolter’s trial on charges he stabbed his estranged girlfriend, Kori Fredericksen, to death in May 2011 and dumped her body down a ravine on Clark County’s Southeast Evergreen Highway.Jurors will receive their instructions and hear attorneys’ closing statements beginning at 9 a.m. today. Jury deliberations will follow.Wolter, 46, is accused of stabbing Fredericksen, 41, more than 70 times in his Vancouver home at 1205 W. 39th St. He is charged with first-degree aggravated murder, which requires prosecutors to prove premeditation and intent. Though it is Washington’s only capital crime, the prosecution is not seeking the death penalty.Wolter’s attorney, Therese Lavallee, has based the defense on claims that fetal alcohol spectrum disorder, as well as a traumatic brain injury Wolter suffered at age 18, caused brain damage interfering with his ability to form intent.Lavallee and Prosecuting Attorney Tony Golik continued grilling a prosecution neuropsychologist Tuesday to rebut each other over whether Wolter had the capacity to premeditate the slaying.Neuropsychologist Michael Daniel of Oregon’s Pacific University had testified Monday that Wolter may have brain damage from fetal alcohol spectrum disorder and the brain injury. However, Daniel said, the damage is not significant enough to prevent him from forming intent or living a normal adult life.
