Investigators have identified a 17-year-old male suspect in the stabbing death of a 19-year-old man at a house party in Mississauga back in May.

At about 1:15 a.m. on May 26, Daniel Smith was at a post-prom house party in the Tradewind Drive and Winston Churchill Boulevard area in Mississauga.

Friends told CP24 at the time that Smith became aware of a physical fight nearby and tried to break it up when he was stabbed.

Paramedics found him at the scene without vital signs. He was rushed to a nearby hospital where he was pronounced dead.

A candlelight vigil was held for Smith at Osprey Marsh later that same day, where several hundred friends and acquaintances came to honour his memory.

On June 21, a 16-year-old boy was arrested and charged with assault causing bodily harm and second-degree murder. He was not identified publicly per the terms of the Youth Criminal Justice Act.

An 18-year-old male, identified by police as Noor Mohamed, was charged with one count of accessory after the fact to murder in connection with the stabbing.

On Wednesday, police identified an additional outstanding suspect wanted for second-degree murder.
