A YMCA parking lot on the city's north side is the scene of a murder investigation.
Officers continue to search for the gunman who shot and killed 36-year-old Deon Johnson on Sandalwood place, just off Karl Road in North Columbus.
Police say it all started with an argument in the YMCA parking lot and escalated to a shooting.
They say the people involved in the crime had no affiliation with this YMCA, but with dozens of children so close by, and a shooter on the loose, the staff immediately locked down the building.
"We were going downstairs and into the gym and they locked down the doors," said 7-year-old, Jayleana Tubbs.
"The reason they were locking down the Y is because if the shooters get in, they might shoot everything down," said 5-year-old, Keondre Tubbs.
Following the shooting, the Tubbs siblings stuck together. They say the last thing they want, is to get hurt, while waiting for their mother.
"I just received a whole bunch of phone calls… from the Y, from my aunt, from friends," said mother, Chawndalya Tubbs. She said people were warning of a shooting outside, while her children were within.
"I feel sorry for what happened to the victim and their family, what they're about to go through, but I'm just happy nothing happened on the inside," said Tubbs.
So many parents rushed to the YMCA with that same fear in mind.
"It made me nervous. I jumped right in my car and came straight here," said mother, Andressa Coles.
Coles says her 17-year-old son, Tyler, was in the gym, when shots were fired. He tells 10TV he didn't hear a thing.
"Just playing basketball and said we can't go nowhere. Somebody got shot in the parking lot," said Tyler Coles.
Columbus Police detectives confirm a man was shot and killed, while sitting in the driver's seat of a car.
The passenger side window was seen shattered, with evidence left behind.
"It's never a right place for anything like this at all, but not at the Y," said mother, Jocelyn Wilson.
Parents tell 10TV they're relieved to find their children safe, but worried a shooter might strike again.
"It's scary. I don't even know if I should bring my kids to the Y tomorrow. They said it's going to be open, but seems like you can't go anywhere and be safe nowadays," said Tubbs.
Police are still looking for the people involved in the shooting. They say they're looking for 3 or 4 people, driving a grey, possibly beige early 2000's model Chevy Impala.
