BUFFALO, NY (WKBW) - Mayor Byron Brown urged the public to cooperate with police and asked witnesses of last weekend's mass shooting to come forward once again on Thursday.
"This crime will be solved," Brown said. "It is just a matter of time."
Brown says police continue to make progress everyday as they search for the gunman who wounded eight people, four fatally, outside City Grill restaurant early last Saturday morning.
"I feel very comfortable that our police department, and our federal and state partners are doing everything that they can to bring the responsible party or parties to justice," the Buffalo Mayor said.
While police look at what happened outside City Grill, state liquor authority investigators are probing what happened inside the restaurant.
"We want to make sure our licensees do the right thing," said authority spokesman William Crowley.
"We wouldn't want them to just have people get into a fight and tell them to take it outside. That's not what we're looking for with our licensees. We're looking for them to be responsible for what happens inside their premises," he said.
Police sources said City Grill closed early on Saturday after a fight broke out at the front door.
At least 100 people who were attending a weekly hip-hop club event were forced to leave the venue.
Moments later, gunfire erupted outside.
A third-party promoter identified as TruLife Entertainment of Buffalo operated the weekly event, according to police sources.
"If a third party is coming in, say they're running entertainment - that's fine as long as the alcohol sales and the control over the alcohol and who's consuming it," Crowley said.
The restaurant, which was licensed to serve alcohol in 2009 and has no past violations, did not return repeated calls for comment.
