NEW GLASGOW, NS - It took less than one hour to identify three individuals spotted in surveillance video outside Big Al's Convenience on the night Amber Kirwan vanished.

RCMP released video and pictures this afternoon showing three young men walking around the parking lot of Big Al's. Another shot showed a man on his cell phone.

Police wouldn't say if the men are persons of interest in the case.

"We were just interested in speaking with these individuals, as you can see on the time stamp, they were in the area at the approximate time," says Const. Bill Rudolph with Pictou County RCMP, "We're asking the public not to read anything into it as the reason why. Aside from they were in the area at the time."

The quick response could be attributed to social media. The pictures and video were posted on an RCMP Facebook site and within an hour, the police knew the trio's names.

Kirwan was last seen leaving a pool hall in the community October 9. Her body was discovered on a logging trail just off Heathbell Road November 5.

Kirwan's death has been deemed a homicide. No charges have been laid, but some wonder when an arrest may be coming.

"I appreciate that the public is very anxious," says Const. Rudolph, "However we want to make sure, the police want to make sure, and I'm sure the public wants to make sure, that is a thorough investigation and it will take time."
