UPDATE1 -- Washington woman found dead after killer posts photos online

USPA News - A 33-year-old Washington state man who is accused of murdering his ex-girlfriend before posting graphic photos of her body online is being sought in the neighboring state of Oregon after leading police there on a high-speed pursuit, authorities said on Wednesday. David Kalac, 33, was last seen at around 1:15 a.m. local time on Wednesday when officers in Oregon spotted the victim`s car in Portland, about 140 miles (225 kilometers) south of Port Orchard, where the murder took place.

The driver of the vehicle sped away when officers attempted to initiate a traffic stop, leading police on a high-speed pursuit. "At approximately Southwest 30th Avenue, the pursuit was terminated as the driver of the suspect vehicle was swerving into oncoming traffic," the Portland Police Bureau said in a statement. "The vehicle was last seen speeding southbound on Barbur Boulevard passing Taylors Ferry Road. Based on the available information, officers believe the homicide suspect was driving the vehicle." Portland Police described Kalac as "armed and dangerous" and urged anyone who sees him to call 911. The murder was discovered on Tuesday afternoon when Amber Lynn, a woman in her early 30s and a mother of four children, was found deceased by her son in her unit at the South Park Greens Apartments in Port Orchard. Her vehicle - a gold 2001 Ford Focus - was missing from the residence. The discovery came just half an hour after an anonymous user of imageboard website 4chan posted three photographs of a woman`s body, claiming to have strangled a Port Orchard woman. The photos show a naked woman - who appears to have been posed on top of a pillow in the center of a bed - with clear ligature marks around her neck. "Turns out its way harder to strangle someone to death than it looks like on the movies. She fought so damn hard," the user said, adding in another post: "Check the news for port orchard Washington in a few hours. Her son will be home from school soon. He`ll find her, then call the cops. I just wanted to share the pics before they find me." It was not yet clear when Lynn was murdered, but filenames of the photos suggest that they were taken just after 1 a.m. on Tuesday. The anonymous user added in his postings that he would attempt to trigger a police shooting when he is found, which prompted police to call in extra officers to the scene as a precaution. "I bought a bb gun that looks realistic enough. When they come, I`ll pull it and it will be suicide by cop," the post said. Kitsap County Sheriff`s Office spokesman Deputy Scott Wilson would not say whether the photos posted online are authentic, but a neighbor who saw the photos said she was convinced that they show the woman who lived at the South Park Greens Apartments. "They (the photos) are graphic and very disturbing," Wilson said of the photos. The victim`s sister, Patti Coppedge, described Kalac as Lynn`s ex-boyfriend. "Please help us find this bastard Dave Kalac. He murdered my baby sister Amber yesterday and took her car," she wrote on Facebook. "This is a horrible tragedy and the family is obviously destroyed by this tragedy." All 16 schools in the South Kitsap School District were put in a modified lockdown on Wednesday morning due to the murder in Port Orchard, but it was later lifted when authorities confirmed Kalac was no longer in the state. "I am lifting the modified lockdown and we can carry on with school as usual," Superintendent Michelle Reid said.
