Video has surfaced on the Internet showing the moments leading up to a shootout involving Clayton County police.
The incident happened Sunday night in Morrow during a standoff between officers and Marquis Harris, 33.
Harris was critically wounded, and several officers were placed on administrative leave.
Investigators said the confrontation started with a custody exchange, when Harris arrived at a QuikTrip gas station on Mount Zion Boulevard to return his daughter to his ex-wife.
The ex-wife's mother, who did not want to be identified, said threats escalated the situation.
"He was talking crazy and threatening my daughter, and the police were listening in," she said. "(He) told her he felt like killing somebody, and she was the first one in line."
Police said they responded to a domestic disturbance and tried to speak with Harris.
By the time the video -- which was posted on YouTube and Worldstarhiphop.com, -- begins, Harris is leaning on a window with his back to the Pars Cars dealership. The video lasts nearly four minutes, but employees said the standoff lasted for more than 20 minutes.
"I'm ready to die," Harris yells at one point.
"My other kids are in the car, it doesn't matter," he says later. "I'm ready to die. We don't have anything to talk about."
Then what sounds like a dying plea.
"Kiss my babies and tell them I love them," said Harris.
A police spokesperson said that's when their crisis intervention training came in to play.
It's now part of the initial training for all new Clayton County police officers.
It deals with, among other things, situations involving those with mental or substance abuse issues when they're in crisis.
In the video, two officers can be seen keeping their distance.
One of them has a stun gun drawn. He is later seen with both hands up, trying to reason with Harris, but shortly after, gunshots rang out.
"Lord have mercy," said one witness.
Clayton County police said there were no officer-involved shootings in the county in 2011. So far in 2012, there have been eight.
