DAVENPORT — A car on a state Highway 2 west of Davenport failed to negotiate a turn, crossed over the center line and slammed head-on into a semi-truck, killing four people, including an infant, Wednesday night. Washington State Patrol identified the four killed as 68-year-old George Friedlander, of Nespelem, and 28-year-old Jake Walter, 32-year-old Georgina Walter and 5-month-old Logan Walter, all of Omak. All of them were in a 1999 Chrysler 300. The semi driver, Gerard Kane, of Clayton, was injured in the crash. Washington State Patrol says it’s unknown if drugs or alcohol played a role. Jake Walter was driving the car and everyone except the infant was wearing a seat belt, the WSP said. The accident closed the roadway for several hours and traffic was detoured onto Miles Creston Road and Highway 25.
