SNELLVILLE, Ga. - Investigators continue to search for the man they said is responsible for a triple murder in a Gwinnett County home.
Three people, including a mother and her 12-year-old son, were killed.
Channel 2's Kerry Kavanaugh spoke to the lead detective who is piecing together this crime. Investigators said they still have no clear motive in the deadly shooting.
Detectives told Kavanaugh they were hoping to talk to the surviving victim of the shooting for the first time Tuesday.
Detectives said Raynord Daniel, 19, was the first to be shot inside a Snellville home on Anderson Livesy lane. The next victim was Joseph McDonald, 12.
Police said his mother, Angelina Benton, was chased outside and gunned down in front of the home.
"In addition a fourth male was also shot outside of the residence," said Detective Deon Washington of the Gwinnett County Police Department.
Police said that man, Justin Cato, 23, fell in ditch along the road and called 911 Sunday night.
identified the trigger man as Robert Bell, 33. They said he gunned down his victims with an AR-15 assault rifle.
"I cannot stress enough how violent this act was and how dangerous this individual is to the public and anyone that would encounter him," Washington said.
Washington said Bell has ties to south Georgia and Illinois.
"The public needs to be very aware of his pictures and if they see him, they need to call 911 immediately," he said.
Investigators are confident they've identified who did this, but what they don't know is why.
They said it appeared Benton was trying to help Bell. Police believe Benton had opened up her home to Bell and his wife. Police said the couple had fallen on hard times and moved in just two weeks ago.
They hope the surviving witness can help them piece together the events leading to such violence.
