On the evening of September 13, 2022, 36-year-old Mary Stephanie Guirand of Stamford, Connecticut, was found dead in the bedroom of an apartment at the Woodside Green complex with a single gunshot wound under her chin. Known as Stefani, she worked as a licensed esthetician and certified nursing assistant and was a mother whose family described her as joyful and the life of the party.

Her 40-year-old boyfriend, Anthony Vines, called 911 that night and told dispatchers he had shot his girlfriend. Police found Vines outside the building; a firearm and a kitchen knife were recovered near Guirand’s body. Vines, a convicted felon, was arrested immediately and charged with criminal possession of a firearm.

A yearlong investigation turned up inconsistencies with Vines’ account. On October 6, 2023, he was charged with first-degree manslaughter with a firearm; bond was set at $1 million. Prosecutors later offered a 30-year plea for manslaughter with a firearm and criminal possession of a firearm, which Vines rejected and the case remains pending trial.

Did anyone in Stamford know Stefani or have information about her last evening?
