Robert Lee Floyd Jr., known as Buttons, was 21 when he was found dead in a vacant house on the 500 block of McElderry Street in Baltimore. Law enforcement determined he had been fatally shot; an obituary gives his date of death as December 28, 2015, and his body was discovered on the evening of December 30, 2015.

A Baltimore native, Floyd attended city and county public schools, participated in recreation center programs, sang in the youth choir at Arlington-Lewin United Methodist Church, and played sports — notably as the starting quarterback for the Randallstown Panthers. He was also described as having been proud of the birth of his son.

There are no public details about arrests, suspects, or any legal proceedings connected to his killing. Does anyone who knew Robert or who was in that neighborhood in late December 2015 have information that could help explain what happened?
