Incident DetailsCause of Death:
Patrolman Frank Dunn was shot and killed while walking his downtown beat.
As he was checking local businesses, a man rounded a corner into a laundromat parking lot and for no apparent reason shot Patrolman Dunn four times in the chest.
A manhunt led to Chicago where the suspect and two of his brothers were arrested five days later after a sharp-eyed night clerk identified them as roomers at the hotel.
All three suspects were extradited after the 25-year-old prime suspect confessed to killing Patrolman Dunn and disposing of the pistol he used in the Chicago River. He was later found guilty of first-degree murder and sentenced to life in prison. His two brothers were charged with harboring a fugitive.
Patrolman Dunn was survived by his wife.
