Amelia M. Griemel Sieckhaus was a woman of 69 who died in St. Louis, Missouri, on February 9, 1956, in a burst of domestic violence that turned a family home into a crime scene. In the public record that preserves her memorial details, the manner of her death is described plainly: she was shot and killed by her husband.
That same day, the violence did not end with Amelia. Two other members of the immediate family—her son, Cpl. Lester F.
Sieckhaus, and her daughter-in-law, Marie Dreher Sieckhaus—were also killed in the same incident, with later summaries of the event treating it as a multiple-victim shooting. A separate listing of the episode as a mass shooting notes three deceased and one injured, underscoring that there was at least one survivor who lived through what happened in the house that day.
In accounts that name a perpetrator, the husband, Henry G. Sieckhaus, is identified as the shooter, the figure at the center of the tragedy. His own death followed shortly afterward—recorded as occurring on February 28, 1956—leaving the impression of a case that was effectively closed by death rather than by courtroom procedure.
No online record located in the sources used here describes any arrest, formal charging, trial, or conviction connected to Amelia’s killing. Instead, the surviving traces of the story point to a single suspect within the household and a chain of deaths that ended before the justice system could play out in public, leaving the aftermath to be carried by the injured survivor and by the family members left behind.
