A third suspect has been arrested and charged in connection with the stabbing death of a man in Duluth, police said.

Yeon Tae Kang Hill is being held without bond on charges of murder and aggravated assault in the Gwinnett County Detention Center, authorities said.

The investigation began the morning of Dec. 8, when a Bank of America customer walking through the parking lot between the bank and an Aldi store on Pleasant Hill Road saw Kwang Ko lying on the ground and called police.

The 32-year-old Duluth man died later of apparent stab wounds.

Tuesday, police arrested Seung Won Lee and Dong Ho Shin, both of Duluth, and charged each of them with murder and aggravated assault. They, too, are being held without bond in the Gwinnett Detention Center.

Police have not disclosed a motive for the incident.
