MEMPHIS, TN (WMC) - A man who died trying to defuse an argument inside a Memphis IHOP was an Air Force veteran with four children.
Family members identified the victim as 27-year-old Devin Wilson. He served in the Air Force and was deployed in Operation Iraqi Freedom.
Wilson met his wife in elementary school and graduated from Sheffield High School.
Wilson's wife, Jessica, said his first love was his four children.
"They're asking for their daddy, they're calling for their daddy, and there's nothing that I can tell them besides he loved them," Jessica Wilson said.
Wilson was shot and killed at the Whitehaven IHOP at 1 a.m. Sunday.
Witnesses said he and a security guard tried to break up an argument between a man and his ex-girlfriend. The ex-boyfriend pulled out a gun and shot the security guard and Wilson.
Police said Wilson jumped in to stop the fight after the ex-boyfriend allegedly choked the woman. Wilson was shot in the head and the security guard was shot in the arm.
Wilson died in the hospital. The security guard was taken to the hospital in non-critical condition.
On Mother's Day, Devin's mother was forced to say goodbye to her son.
"That's the day that I had to make the decision to let them turn the machine off and let my son go," Wilson's mother, Katina Rounds, said.
Wilson's family members said they're not surprised by his courageous final moments.
"We have to do something, you just can't stand by and let that happen. That was Devin," Rounds said.
Wilson dreamed of opening a community center for youth in the Whitehaven neighborhood.
"He wanted kids to have a place to go to without being harmed," Jessica said. "He [shooter] took a life away from all of us. His momma - on Mother's Day. That's no way to celebrate."
His memory lives on and is forever connected to the day he passed away.
"Every Mother's Day will be filled with Devin's day, we can know that," Rounds said.
