Buffalo gunman had plans to continue his killing rampage: Commissioner

Payton Gendron, the alleged gunman who shot fatally 10 people in Buffalo, New York, on Saturday, would have continued his rampage if he had not been stopped, Buffalo Commissioner Joseph Gramaglia told ABC News.

“We have uncovered information that if he escaped the [Tops] supermarket, he had plans to continue his attack," Gramaglia said. "He had plans to continue driving down Jefferson Ave to shoot more black people ... possibly go to another store [or] location."

Gendron, wearing military fatigues, body armor and a tactical helmet, allegedly shot four people in the parking lot of a Tops supermarket around 2:30 p.m. Saturday, three fatally. He proceeded inside the store where he was confronted by a retired Buffalo police officer working security, police said. The gunman then proceeded to shoot nine more people inside the store, police said.
