David Michael Kalac, the Washington state man accused of killing his live-in girlfriend and posting photos of her body online, surrendered to authorities in Oregon and is in custody, sheriff's official said. He has been charged with second-degree murder involving domestic violence after the body of Amber Lynn Coplin, 30, was discovered in the Port Orchard apartment the two shared. Kalac, 33, turned himself in to a Clackamas County sheriff's deputy in the town of Wilsonville, about 20 miles from Portland. A person claiming to be the killer posted photos of a woman's naked body to the online forum 4Chan. Police said in court documents Wednesday that the online photos matched the crime scene. They said they have no reason to believe Kalac did not post the photos online.
