One man accused of shooting another man Saturday evening is in police custody after a SWAT standoff in southwest Atlanta, police said.

Police and homicide investigators were warned about 6 p.m. the suspected gunman, Nathaniel Mathis, may have barricaded himself inside the residence at 72 Polar Rock Road so SWAT was alerted, Kim Jones, a spokeswoman for Atlanta police said.

Neighbors in the area were ordered to stay in their homes.

One neighbor spoke to Channel 2 Action News through a screen door.

“It kind of worries me a bit because there’s children that play around here and this is a park, like a family environment,” the neighbor said.

Family members of both men involved told Channel 2 the gunman killed his sister’s boyfriend, 34-year-old Rod Benton.

A woman who identified herself to Channel 2 as the gunman’s mother said she would have been able to talk some sense into her son, but police wouldn’t let her near the scene.

A standoff lasted more than four hours before SWAT arrested Mathis without incident, Jones said.

Murder warrants are expected to be filed against Mathis, Jones said.
