David Edward Tiscareno, 22, was suspected of killing Topeka police Corporal David Gogian, 50, and officer Jeff Atherly, 29, as they approached a car he was in early Sunday evening outside a Topeka supermarket, authorities said.
Tiscareno fled, but hours later police surrounded a house nearby, acting on a tip from a Topeka resident that the suspect in the shooting of the policemen might be there, according to the Shawnee County Sheriff's Department.
After several attempts to contact Tiscareno in the house, police fired tear gas canisters into the structure, authorities said. Tiscareno exited the house, firing a single shot as police returned fire, they said. He was pronounced dead at a local hospital.
Gogian was hired by the Topeka Police Department in 2004, and Atherly had worked there since 2011. (Reporting by Kevin Murphy and Colleen Jenkins; Editing by Greg McCune and Dan Grebler)
