Helmuth Schmidt

Helmuth Schmidt was an American con-man, swindler, and suspected serial killer. From 1913 to 1917 he was suspected in the swindling of at least three women and was connected with the deaths or disappearances of at least two women. After his death, following the search of his properties, he was connected to the murders of three more women, with additional located jewelry and watches indicating other possible victims in New York and Missouri.
Known or suspected victims.
After the discovery of Pallatinus' remains, Schmidt's widow Adele Ulrich noted that Schmidt had allowed her to take a small peek into the cellar, where she later alleged the authorities would most likely find the bodies of Anita Schmidt and Greta Darsch.
Arrest and suicide.
Upon his arrest, Helmuth confessed that he had burned Steinbach's body, but alleged that she had killed herself with poison following his refusal to instantly marry her and a subsequent quarrel on March 11. Fearing that his wife and daughter would return soon from the cinema, Schmidt dragged the body to the cellar, lifted it through a window and then buried it under his porch. Three months after the incident, he claimed that he dug up the body, cut it up with a cleaver and then burned the pieces in the furnace. She was his last known victim. He committed suicide in his jail cell in 1918.
