A 20-year-old male, who was not named by police, has been arrested.
Bruner, 34, died in Nassau early Sunday. According to authorities, Bruner was shot in the neck while trying to help a woman who was being mugged on the street by three men wanting to steal her jewelry.
The Royal Bahamas Police Force have confirmed that they took Antone Bastian into custody for questioning Monday afternoon.
A third suspect, 18-year-old Leo Bethel, remains at large.
Bahamian police are investigating the shooting and reaching out to the public for any information.
Bruner's parents live on Chicago's Northwest Side. Family members say the man was a former special education teacher who was following his passion of tall ships by working as a first mate on the Liberty Chipper , which was moving through the Bahamas. The ship was docked in Nassau when the shooting occurred.
