TOPEKA, Kan. – A man with a history of theft and weapons convictions gunned down two police officers investigating possible drug activity in a Kansas grocery parking lot, and was later killed after an armed standoff, authorities said Monday.

Kyle Smith of the Kansas Bureau of Investigation identified the man who opened fire on Topeka police Cpl. David Gogian, 50, and Officer Jeff Atherly, 29, on Sunday night as 22-year-old David Tiscareno of Topeka.

Shawnee County Sheriff Herman Jones said Tiscareno was seated behind the driver's seat of a car stopped in the parking lot of a Topeka grocery store when police ordered the occupants to get out. After shooting two of the three responding offers, Tiscareno got back into the car and drove from the scene. The third officer returned fire, Jones said.
