Toronto Police Services have released photos of a second person of interest in connection with the murder of Toronto millionaire philanthropist Glen Davis.
In the photos, the man has dark brown hair, is wearing dark sunglasses, jeans and a dark shirt.
One other suspect, with brown hair and wearing a boxy coat, was caught on video surveillance at the same time and is also being sought in connection with the case.
Police are urging the public to contact authorities if they have any information regarding the identity of either man.
Davis, 66, was found in an underground parking complex in May and later died from gunshot wounds.
"Nothing in Mr. Davis' background would cause us concern or would lead us to believe that he put himself at risk through his endeavors, be it professionally or personally," Det. Peter Moreira said during a press conference.
The parking area was used by an exclusive group of attendants, visitors and restaurant patrons police said.
Authorities believe Davis was targeted for the grisly crime, but a motive is still not yet clear.
Police believe the suspect and the person of interest knew each other.
"We've been able to narrow it down to a few theories that the evidence most likely supports. We're not hanging our hat on any one of those theories just yet. We're going to let this play out," Moreira said.
Davis, described as shy and quiet by friends, donated millions of dollars to various wildlife causes.
He had just had finished lunch with a WWF associate when he was killed beneath the WWF office building on Eglinton Avenue, near Mount Pleasant Road.
Investigators are also trying to determine if a baseball bat beating he sustained in December 2005 is somehow linked to his murder.
Police remained tight lipped about the investigation but did say they are working with RCMP in another province on the case.
Anyone with information regarding the identities of the people in the images is asked to contact the Homicide Squad at 416-808-7400, Crime Stoppers anonymously at 416-222-TIPS (8477), or online at www.222tips.com.
