CBC News has learned Dhak, a south Asian, and a Caucasian man believed to be his associate were gunned down Monday at the Executive Hotel and Conference Centre at Lougheed Highway and Gilmore Avenue in Burnaby, B.C., just before noon.
Dhak's brother, Gurmit Dhak, was shot and killed outside the Metrotown mall in Burnaby in October 2010.
On Monday, the body of a tattooed man could be seen slumped outside the front doors of the hotel, surrounded by shattered glass from the doors and windows of the hotel lobby.
A second body appeared to be lying just inside the lobby of the hotel.
Police, who spent Monday night trying to piece together what happened, are calling the shooting "brazen" and "cold," saying it was traumatizing for hotel staff.
It's not yet clear whether the shooting happened outside the hotel or whether the men were shot through the glass.
B.C. Liberal MLA Kash Heed, a former solicitor general, told CBC News he met the Dhak brothers when he was a Vancouver police officer.
Heed said the boys grew up in South Vancouver when late gangster Bindy Johal was making a name for himself.
"When Johal and Cheema and the Dosanjh brothers were involved in some of their violent activity, Sukh and his brother were very young school age children that were easily influenced by that type of lifestyle," said Heed.
Heed said the names will change, but the bodies will pile up unless something is done.
"If we were to think long term and put in some true prevention strategies, maybe we won't have this public display of violence."
There have been no arrests and police have yet to issue a description of suspects.
