The 30-year-old man shot dead in front of his wife in Cherokee Triangle was armed and shot back at the suspect, Louisville Metro Police said, prompting a discussion on gun violence among neighbors in the area.

Jason Spencer, a Humana employee and creator of the Louisville Humor Twitter account, died right off Everette Avenue in the Highlands neighborhood on Sunday evening while visiting his wife's family. He was married just 10 days before his death.

Ian and Stephanie Mutchnick were inside their home Sunday and said they heard five or six gunshots ring out around 8 p.m.

"When I opened the door, it felt like the violence was over," Stephanie Mutchnick said. "When I stepped out on the porch I saw Mr. Spencer’s wife, and she drew my attention and then I saw his body lying on the ground."

Stephanie yelled for her husband while she called the police. Ian, a pediatric neurosurgeon, ran out and started doing chest compression on Spencer's body. But it was too late.

“I did do chest compressions for a bit in case something might have told me we were heading in a good direction,” Ian Mutchnick said. “But I didn’t think we were ... I’m deeply saddened by his passing. I was there to hold his head as he had his last breaths and the emotions I experienced then were unique.”

Police arrested a 15-year-old boy in connection with the shooting, police spokesman Dwight Mitchell said Monday. Police found the boy later Sunday with a gunshot wound near the intersection of 11th and Hill streets in the Park Hill neighborhood.

Police are still looking for a second suspect in the death of Spencer.

A Tuesday police statement said Spencer "had a gun" and "returned fire" at the suspects, striking one of them and causing non-life threatening injuries.

While Ian Mutchnick said he was deeply saddened for Spencer's family, he was also angry about the state of gun violence in Louisville – and America as a whole.

“While each one of those individuals felt like they were using their guns for something they felt was justified, the ownership and use of a gun has one purpose: to enforce an individual or a small group of individuals will over another," Mutchnick said.

Spencer's death is the 98th homicide in Jefferson County, according to a Courier Journal count. LMPD handled 118 criminal homicide investigations last year – the most in its 14-year history.

“I think that the larger issue is the danger that the presence of those guns pose to literally dozens of people in the surrounding area is something that needs to be addressed," Mutchnick said.

Other neighbors also said they were shocked about the shooting in Cherokee Triangle.

Roger Hilkert lives close to the area, just off Cherokee Road. He said he's only aware of a handful of homicides in his neighborhood since moving there in 1983.

"I had two sets of thoughts when I heard of the shooting," Hilkert said. "One was that this shouldn't happen in a neighborhood like this. The other was that it can happen anywhere."

Juliet Gray, a 10-year resident who lived just houses away from the crime scene, said she came back from dinner to see her block surrounded in police tape.

"It's really frightening," Gray said. "Gun violence? Gun violence right here? My house was the police line that was unnerving."

Police are still searching for a second suspect. Anyone with information is asked to call 502-574-LMPD.
