Toronto police say they've run out of clues in their search for a suspect five years after a shooting at Dupont subway station that left a TTC fare collector seriously injured after being shot in the shoulder and neck.

On Feb. 26, 2012, the suspect approached the TTC collector's booth with a gun in their left hand, walked away briefly after the collector hesitated to hand over money, then turned around and fired shots through the glass barrier. The suspect then fled empty-handed.

"There was no provocation. This is just some type of animal act committed by a coward for no good reason," said Staff Insp. Mike Earl at a press conference Monday morning. "We have a hardworking person that is now suffering probably for the rest of his life with injuries and medical issues."

The same suspect had actually robbed the subway station two times before.

'Clues dried up'

But five years later, investigators have no new leads.

"We checked video surveillance in the area; we have nothing further," Earl "Our clues have dried up. We are looking for anything that would point us in the right direction."

Police said after the shooting, the suspect fled the station and went to a parking lot at Spadina and Macpherson avenue and entered a silver vehicle.

Police believe the suspect, who wore masks in all three robberies, stands between 5-2 and 5-5, and has a "stocky" build. He or she also used and carried a weapon in their left hand.

"After the shooting, this person has literally disappeared," Earl said. "I'm hoping this information does get out there and nudge someone's memory."

$25K reward

Investigators are hoping the suspect may have confided in someone about the shooting during the last five years — or that anyone who may have withheld information previously will come forward now.

The TTC said a $25,000 reward still stands for anyone that can provide police with information that leads to the arrest or conviction of the suspect.

The fare collector that was shot has not returned to work since the incident and is still on long-term disability, according to TTC spokesperson Brad Ross.

"This senseless crime shook the TTC and caused us to do a number of things to make our employees safer," he said.

The TTC has taken measures to reduce the amount of cash handled by TTC fare collectors such as ensuring all booths can accept credit and debit cards. They also strengthened the glass divide between the employees and riders so that it's more resistant to bullets.
