Nearly a year after two people at an OVO fest after-party were shot to death, Toronto police are renewing their call for witnesses and information in the case.

Ariela Navarro-Fenoy, 26, and Duvel Hibbert, 23, were shot dead after an altercation took place at Muzik, a popular nightclub hosting an after-party where Toronto rapper Drake was supposed to attend, on August 4, 2015.

Several thousand people were in attendance when the shooting occurred. Hibbert – who police believe was the target of the shooting -- was found inside the club while Navarro-Fenoy was hit by a stray bullet outside as she tried to hail a cab to flee the chaos that had broken out.

Three others suffered non-life threatening injuries while caught in the crossfire.

Though no arrests have ever been made in the case, police said they are still looking for two people of interest.

Det. Omar Khan would not tell reporters how authorities identified the men.

"We've had a great deal of co-operation, it's just that we need more - we need more co-operation and assistance from the public in order to advance the investigation," Khan said at a news conference Friday morning.

Navarro-Fenoy’s sister spoke in tears as her father stood quietly next to her, describing the loss of her sibling as a “horrifying nightmare.”

"Losing someone you love and care for to a senseless act of violence and murder is a horrifying nightmare. A nightmare my family and I have had to endure the past year," Aluen Navarro-Fenoy said.

Calling Ariela her “soulmate,” Aluen too pleaded for members of the public to come forward with information.

“We can’t act like Ariela’s murder never happened,” she said through sobs. “We need your help in bringing Ariela’s murderer to justice.”

“We need any information that you can think of. Any information is good information, and even if you’re scared, there are ways to cope with that,” Aluen continued.

Khan said police have collected a lot of video footage of the area that night but are still looking for more video that captured the chaos.

He added that close to 4,000 people had flocked to the area for the after-party and that no information is “insignificant or too little for the police investigation.”

“This was a very reckless, brazen attack in a public place,” he said.

The first suspect is described as a black male between 25 and 26 years old, approximately six-feet to six-feet-one in height with a fresh buzz cut. Khan said he was last seen wearing a bright purple crew-neck sweater with a colourful design on the front and dark blue jeans.

The second suspect is described as a brown-skinned male between 24 and 28 years old, approximately five-foot-ten or five-foot-eleven in height. He was last seen wearing a yellow plaid and burgundy button-up shirt.

Anyone with information is asked to call police at 416-808-7400 or Crime Stoppers at 416-222-TIPS (8477).
