On November 19, 1956, two Michigan State Police troopers — Bert Pozza, 27, and George Lappi, 27, of the Flint post — were shot and killed with a deer rifle after responding to back up another trooper at the scene of a domestic disturbance in Genesee County
When the first trooper arrived, the suspect threatened him with a rifle. As Lappi began to negotiate with the suspect, he inadvertently exposed himself and was shot. Pozza attempted to find cover and was also shot.
The suspect was taken into custody a short time later and died of pneumonia several days later while in custody. They were the 19th and 20th MSP officers to die in the line of duty.
