BUFFALO, NY (WKBW) -- A Buffalo homicide may have triggered the bloody mass shooting at City Grill restaurant, according to police sources with knowledge of the investigation.
Lawrence Bradberry, Jr, 30, was shot and killed on Durham Avenue on August 12, just a few days before eight people were shot, four fatally, outside City Grill restaurant.
Bradberry was an acquaintance of Willie McCaa, one of the City Grill victims who died, the sources said.
Riccardo McCray, 23, of East Ferry Street, has been charged with four counts of second degree murder in the City Grill shootings.
Police have called him the alleged lone gunman in the case.
McCray pleaded not guilty to the charges at his arraignment in Buffalo City Court on Thursday.
Judge Jeffrey Voelkl denied bail, so McCray is being held at the Erie County Holding Center in isolation, according to a high-ranking jail source.
The case will be presented soon to an Erie County Grand Jury, District Attorney Frank Sedita said on Wednesday.
McCray has proclaimed his innocence, said his defense attorney Terence McKelvey.
"His position is adamant that he's not guilty. He's adamant in his position that he would have had no motive to engage in any such heinous kind of crime," McKelvey said.
