Police are searching for a man they say stabbed a 58-year-old delivery driver outside a Decatur mattress store.

An arrest warrant for aggravated assault has been issued for Jordan Christopher Brown, 29, Decatur police Lt. Jennifer Ross said.

Police said Brown should be considered armed and dangerous. Anyone who sees him is cautioned not to approach him and to call police immediately.

The delivery driver, who was identified by his family as Jeff Gwinn, had stopped by his job in the 2700 block of East College Avenue sometime before 1:30 a.m. March 15 to get something out of a truck when he noticed someone inside, Ross said previously.

Police said Gwinn confronted the man inside the truck — who apparently entered the cab by tearing through a sheet of plastic that covered a damaged window — and a struggle ensued.

“The victim confronted the male and asked why he was in the truck,” Ross said. “The male responded by saying, ‘This ain't your truck, it's abandoned.’”

Brown tried punching Gwinn before pulling out a sharp object and thrusting it at him, Ross said, adding that the victim later told police “his shirt became wet.”

According to police, the man suffered multiple cuts before getting into his car and attempting to drive away. He lost consciousness and hit another vehicle near Memorial Drive and Columbia Drive. He was taken to a nearby hospital in critical condition.

Ross said Thursday Gwinn is recovering from his injuries. His daughter, Jamila Cleveland, told Channel 2 Action News he has not returned to work because he’s unable to walk.

“I know he's having a hard time,” she said. “He's in a lot of pain, but it’s just such a blessing that he's here.”

Cleveland said Gwinn, who is a grandfather, has stab wounds across his neck, arms and legs.

The stabbing suspect left the scene on foot. A surveillance photo of the suspect, identified as Brown, was taken from a camera at the nearby Avondale MARTA station, police said.

Gwinn’s family wants the man off the streets for the safety of the community, but Cleveland said they are not angry with him. They suspect he was not aware of the consequences of his actions, she told Channel 2.

Anyone with information about Brown's whereabouts is asked to contact investigator Tiffany Edwards at 678-553-6664. Tipsters can remain anonymous, and be eligible for rewards of up to $2,000, by contacting Crime Stoppers Atlanta at 404-577-8477, texting information to 274637 or visiting the Crime Stoppers website.

Police said the man inside tried to take Gwinn's truck but ended up stabbing him seven times with a knife before walking away.
