Delano Coombs shooting can be solved with DNA match, police say

Toronto police say they now have a description and DNA of the suspect involved in the murder of Brampton resident Delano Coombs.

Coombs, 27, was ambushed in his vehicle and then found shot in a laneway at 4020 Dundas Street West on May 10, 2012. Police say multiple suspects and firearms were involved in the homicide. Coombs died of his injuries a short time later in hospital.

After talking to witnesses and further investigation, police say they are now looking for a black male, around 20 years old, five feet ten inches tall with a slim build. The suspect is believed to have had his hair braided with it slightly long at the back.

Homicide Det. Tam Bui said police have obtained a DNA profile from a sweatshirt that the suspect wore, however, the DNA profile has no match on the National DNA Databank.

"I consider evidence like this...kind of like a time bomb...something that's sitting in their lap waiting to go off because whether it's 10 months from now or 10 years from now, one day we might develop a DNA profile and at that time we are going come knocking on your door," Bui said. "We only have to be lucky once but you have to be lucky every single day for the rest of your life."

Police say they have located a sweatshirt worn by one of the suspects with an 'STG Entertainment' logo on it.

STG Entertainment is a Toronto based urban entertainment and promotions company. Police believe the offender has some type of connection with the company.

Bui said Coombs had no relationship with the business.

Coombs's sister spoke to the media, asking whoever was responsible for her brother's death to come forward.

"My brother was very loved. He was a brother, an uncle, a son, a nephew, cousin...I would like whoever did this to turn themselves in," she said. "Our family, we're getting by daily but it's very hard."
