Jerome, Idaho (KMVT-TV) - The Idaho State Police say they will be dedicating their Jerome headquartered district 4 building to a Police officer, who in 1935 was gunned down following a pursuit. The officer killed was the first in Idaho, who died in the line of duty. State police say that it all happened on Saturday, November 23, 1935 when Mildred Hook was kidnapped off the streets in Tacoma, Washington by Douglas F. Van Vlack. Police throughout the Northwest were alerted to be on the lookout for the couple. At 2:00 P.M. on Monday, November 25, 1935, Idaho State Trooper Fontaine Cooper and Twin Falls Deputy Sheriff Henry C. Givins spotted Van Vlack's 1931 Ford coupe on Highway 30 near Buhl. The officers pulled Van Vlack over. As Trooper Cooper approached the car, Van Vlack pulled out a pistol and shoot Trooper Cooper, killing him instantly. Van Vlack then shot Deputy Givens three times; Deputy Givens died two weeks later. Trooper Fontaine Cooper was the first trooper killed in the line of duty. On Friday, September 14, 2012, at 1100 A.M., the Idaho State Police will dedicate the District Four Office in the memory of Fontaine Cooper. Current and retired officers, citizens, elected officials and the media are encouraged to attend this historic dedication. The address is 218 West Yakima in Jerome.
