Police are still looking for answers after a pizza delivery driver was shot and killed on Wednesday night in Columbus.

Investigators are looking for answers after a delivery driver was gunned down in the street.

Jim Crabtree was a family man trying to do his job on Wednesday night.

His last delivery was to an address at Cassady and 6th Avenue.

It’s still a shock to Cindy McClain that it was the last day of Jim Crabtree’s life on Wednesday. “He was a gentle giant, he didn't do anything to hurt anybody,” mourns McClain.

Jim had lived next door to the McClain’s for about 20 years. She says he was a single dad most of that time to his son Nick and daughter Courtney. He was recently remarried and had a 5-year-old.

Cindy and her husband got the devastating call from Nick at 3:30 in the morning. “He was bawling his eyes out to me and my husband,” McClain recalls.

Nick told them his dad was shot and killed while at work as a delivery driver for Grandma's Pizza.

The shop owner told 10TV Jim wasn't even supposed to be working and had switched shifts so he could take his youngest daughter trick or treating on Thursday.

A 911 call reveals the how the scene played out:

Dispatcher: Why do you think the pizza man was shot? Because he heard the shots?

Caller: Because he said he went out to pay for the pizza, and the man is out there gagging for breath and he said the little dudes across the street from me (have been) out there shooting, like for multiple days.

Ashley Lipson placed that 911 call. She and her friend ordered the pizza, heard the shots and later saw Jim on the ground outside.

As for McClain, she says Crabtree was one-of-a-kind. “You don't find dads like that anymore that live and breathe for his kids the way he does.”

Police believe robbery was the motive in the killing of 45-year-old James Crabtree. Several persons of interest are being interviewed as police piece together the final moments of Crabtree’s life.
