I've been doing genealogy research on people from my mother's home town of San Pietro Avellana.
The searching has led me to Denver and the 1910 murder of Dorinda Labate Cellante possibly by the same person who murdered Maria LaGuardia. I've found many Denver Post articles about Cellante's murder and the connection to Angelina Garramone. No one was ever convicted (that I can find) for Cellante's murder.
I did find that Garramone was released from prison in 1922 after serving about 11 years.
The connection to my mother's hometown is that Dorinda Labate was born in that town. She first married Felicito Frazzini in 1886 and then Domenicantonio Labate in 1899 and then Clemente Cellante in 1905.
Felicito Frazzini was the brother of Prospero Frazzini who owned a bank and grocery in Denver. My mother's maiden name was Frazzini and I'm related to that family.
