Connor Daniel O’Callaghan, 30, was found dead with Bonnie Galloway, 38, on February 13, 2022, inside a shed at 2141 S. Erie St., Wichita. Both had sustained gunshot wounds to the head. They had been living in the shed with the homeowner’s permission.

Investigators linked the killings to a robbery. Justin Macormac, 27 at the time, was identified as the primary suspect; he was arrested on an unrelated matter on February 14, 2022, and later charged. Macormac pleaded guilty to multiple counts including first-degree murder and voluntary manslaughter and received a life sentence with parole eligibility after 71 years and one month. Brandon Prouse Jr., 23, pleaded guilty to aggravated battery and was sentenced to more than 20 years; he was said to have helped plan the robbery with Macormac. The pair went to the shed seeking fake Percocet pills laced with fentanyl known as blues. During the robbery Macormac shot both victims while they were sitting on a couch, then took guns and cellphones before leaving.

If anyone knew Connor O’Callaghan, his movements before February 13, 2022, or the people who stayed at that Erie Street address, please share what you know.
