Ottawa Police are hoping to speak with seven men they think could help with the investigation into the shooting death of Ashton Dickson .
Dickson, 25, was gunned down on June 26 on Rideau Street, just east of Chapel Street.
On Tuesday, police released photos of seven people they think could be potential witnesses to the crime.
Anyone with information is asked to contact Major Crime Unit Detective Jim O'Connell-Smith at 613-236-1222, ext. 5149.
The Mingle Room, the bar outside which Dickson was shot dead, closed late last month.
