Ben Siebels (actually John B. in this enumeration) was listed individually in Caney Township, Montgomery County, Kansas, in the 1930 census. He is listed as a gas station attendant in this reference which was located on Ancestry.com . His parents (Ben and Mary) are also enumerated on the same census page.
The one clipping shown in this blog post was located on Genealogy Bank and comes from the Dallas Morning News of 30 December 1930. It was located (as can be seen in the image) by searching for Everett Haldiman. There are several name variants that I could also search for as I attempt to learn more about this case. It is certainly tragic.
Ben Siebels maternal grandmother was Annepken Hinrichs Ufkes Habben (1831-1905).
