The injured 27-year-old man was taken to a hospital with serious injuries.
After the shooting, police tracked a suspect to a home on Avon Lake Drive. The person barricaded himself inside an apartment building, police said.

Andrews called the barricaded person a "person of interest." but did say police felt "very strongly" that the person was connected to the shootings.
On Thursday evening, Durham SWAT team officers surrounded the building and were using a loudspeaker in an effort to get the barricaded person to come out.
Around 9 p.m., police used a flash bang in an effort to startle the person inside and induce them to come out. That didn't appear to work. But DPD's Selective Enforcement Team (SET) entered the apartment around 10:30 p.m. and took the man into custody.
He was identified as 26-year-old Erick Ray Hudson of Durham.
Hudson was arrested and charged with murder and assault with a deadly weapon with intent to kill inflicting serious injury.
Earlier, police officers were seen hiding behind cars with guns drawn as investigators combed the scene and made sure residents were not in the line of possible gunfire as people who live there arrived home from work.
Several apartments were evacuated during the incident Thursday night.
The incident does not appear to have been random, investigators said. Police added that the suspect and victims knew each other.
Witnesses told ABC11 that they heard at least eight or nine gunshots. Witnesses also said someone was standing on a third-floor balcony and shot down at someone in the parking lot.
One woman, who did not wish to be identified, told ABC11 that she was unloading groceries with her children when the shooting happened
"They were running back and forth helping me take the groceries back upstairs and in the midst of all of this going on, I heard the shots," she said. "When I heard the shots, I seen the guy."
She said she tried to get towels to help stop the bleeding and help the woman but it was too late.
"I was yelling at my kids like go upstairs, go upstairs, go upstairs," she said. "I'm running behind them, and he's behind me, and I'm trying to make it such that he doesn't get in my door.
"My kids saw this," she added. "My kids watched this - they were throwing up."
She added that this is not the first shooting that's happened at this complex.
"I'm just a single mom from Buffalo trying to survive, and here, here I feel like I'm in a war -- every day," the woman said.
Police said the incident did not appear to be related to any prior shootings in the area.
Hudson is being held in the Durham County Jail without bond.
