Authorities on Tuesday arrested a man they believe fatally shot another man near Goose Creek on Sunday. 

Antwon Gregg, 32, was taken into custody Monday night, according to the Berkeley County Sheriff's Office.

The Goose Creek resident faces one count each of murder and possession of a weapon during the commission of a violent crime. 

Eugene Fordham, a 64-year-old Moncks Corner resident, was visiting a home at 3501 Harbour Lake Drive when he was shot, according to County Coroner George Oliver. Investigators believe he was shot while answering a door at the home on Sunday, the Sheriff's Office stated. Although authorities have yet to disclose a possible motive, Berkeley County Sheriff's Office spokeswoman Carli Drayton said that the two are brother and sister and that the shooting stemmed from an incident that "began over 14 years ago."

Fordham was discovered with a gunshot wound to the chest by deputies responding to a call shortly before 6 p.m., according to the Sheriff's Office. 

He was transported to a hospital, where he died, the Sheriff's Office stated. 

Earlier Monday, authorities arrested Andrea Anna Octivia Gregg, 29, of Otranto Road in North Charleston, and charged her with accessory after the fact to murder.

Fordham’s death is the third homicide investigated by the Berkeley County Sheriff’s Office this year, according to a Post and Courier database. There have been 12 slayings in the tri-county area in 2019.
