KITCHENER -- Brantford police are conducting a homicide investigation after a 20-year-old man died from gunshot wounds.

Emergency crews were called to a residence on Diana Avenue just after 12 a.m. on Wednesday.

A man was found in serious condition and was transported to hospital, but later succumbed to his injuries, police say in a news release.

Police say the incident is being investigated as a homicide and do not believe it was a random incident. They expect to be on scene for the rest of the day.

"It's quite surprising because it's a soft-spoken neighbourhood," one resident tells CTV News. "A lot of children here, a lot of families here that are very happy and very good. I've never seen anything like this before."

Neighbours said they heard gunshots on Tuesday night before police arrived at the scene.

"I jumped out of my bed and I saw all the police, all around." Melissa Aristil said. "There was a lot of police on this side and a lot of police on the other side."

Anyone who may have been in the Diana Avenue area between 9:30 p.m. Tuesday and 12:30 a.m. Wednesday and saw or heard anything suspicious is asked to contact Brantford Police Service, or report anonymously with Crime Stoppers.
