'He was a really good guy'

Hanna Locke and Deshawn Gibbs – two of Patten's friends who spoke with CBC Toronto – expressed shock and sadness at his killing.

"He was a really good guy. He was in the wrong crowd but he was a really good guy deep down and it's really terrible to see my friend go through that," Locke said.

"I've never heard of him being involved with guns or anything like that. It like shocked me a lot when I heard about it."

Gibbs said he last saw Patten less than a week ago.

"[We were] hanging out just like friends do, you know. He was a good guy," Gibbs told CBC News.

"It's just a crazy situation you know. A man loses his lift at 18, still so young, still got a lot of life to live."

The shooting was one of three fatal attacks that took place around the GTA overnight.
