Police Officer Frederick Kaiser was killed when a bomb exploded in the department's Central Police Station.
Officer Kaiser was a Spanish-American War veteran and had served with the Milwaukee Police Department for 12 years. He was survived by his wife and is buried in Section 4 of Forest Home Cemetery, Milwaukee, Wisconsin.
Nine Milwaukee police officers and two civilians were killed when a bomb exploded inside of the Central Police Station at the intersection of Broadway and Oneida Street (modern-day Wells Street).
The bomb had been found in an alley between a church and its adjacent mission house. A church member and citizen brought the bomb to the police station and gave it to Station Keeper Henry Deckert, who took it to the assembly room as roll call was starting.
As the officers examined the device it exploded, killing eight officers inside of the room, one officer in the radio room above the assembly room, and two civilians who were inside of the station.
No suspects were ever identified but it was believed at the time that the bomb had been placed at the church by anarchist sympathizers.
