TULSA, Oklahoma - Two men are dead after a gunman opened fire at a Tulsa electronics store Saturday about 2 p.m.

Tulsa police said surveillance video from Best Buy, 5520 East Skelly Drive, showed a man darting through parked cars to shoot "intended target," 34-year-old Scott Norman, in his back.

Stray bullets also shattered the glass at the front of the store, and one hit Graydon Brown, 58, who was inside shopping with his young daughter, Tulsa Police Sergeant Brian Carlile said.

The two victims were transported by EMSA to a Tulsa hospital in critical condition. Both men later died. 

A search of Oklahoma Department of Corrections records shows a Tulsa man with the same name and birthday as victim Scott Norman who has served time for drug possession and driving under the influence. That Scott Norman has several tattoos indicating he is a member of the Crips gang.

Police have not confirmed that the victim is the same man, but they did confirm the date of birth.

After the murders, Carlile told News On 6 there was no concrete evidence that the shootings were gang-related, but didn't rule it out.

"My mind is still going over it right now," Best Buy shopper Joshua Davis said. "I'm not sure what to really think about it."

Davis was inside the store, which is near Interstate-44, when a man started shooting.

"I just feel very sorry for the family that experiences these losses," he said.

Davis said he went inside the store about 20 seconds before the shooting started.

His wife was waiting in the car.

"I heard some banging," Michelle Davis said. "I thought [Joshua] was banging on the door to let him in, then I saw a red pickup truck speed off, and then [Joshua] called me and told me to lock the doors and get down."

The shooter, described as a 5-foot-8, 150-pound black man, initially left the scene on foot, then jumped into a small, dark-colored two-door car, Carlisle said.  Police are still looking for the car.

Two vehicles were later towed from the store's parking lot.

Detective Dave Walker said police are trying to determine if the suspect left any evidence on the cars while he was running through the parking lot.

After the shooting, Graydon's daughter was released to her grandparents, police said.
