BUFFALO, N.Y. (WIVB) — Buffalo Police Commissioner Joseph Gramaglia on Monday provided an update on the investigation into the mass shooting that occurred this past Saturday.

Utilizing special equipment, the FBI will be working inside the Tops store where the shooting occurred. Gramaglia says work outside the store took place on Sunday.

On Saturday, 10 people were killed and three others were injured at the Tops supermarket on Jefferson Avenue. Police said the 18-year-old accused of committing the atrocious act of white supremacist terrorism has been identified as Payton Gendron — a resident of Broome County, near the New York/Pennsylvania border.

Gramaglia said the investigation into the attack would be a “slow, methodical process.”

“You know the officers,” Gramaglia said. “They’re resilient, they’re tired, but they’re gonna be here as long as it takes.”

On Sunday, police released the names of the 10 victims who were killed and three others who were injured. They ranged in age from 20 to 86 years old.

  • Roberta Drury, 32
  • Margus Morrison, 52
  • Andre Mackneil, 53
  • Aaron Salter, 55
  • Geraldine Talley, 62
  • Celestine Chaney, 65
  • Heyward Patterson, 67
  • Katherine Massey, 72

Erie County Sheriff John Garcia used to work alongside Aaron Salter, who recently retired from the Buffalo Police Department.

“What a hero,” Garcia said. “He actually stopped the shooter from continuing in the store for enough time for him not to kill more people.”

Garcia said called the scene “horrific.”

“The amount of damage that a round from an AR-15 does to a human body is just horrible,” he added.

News 4’s Gabrielle Mediak was also joined by Mayor Byron Brown, who spoke on investment in Buffalo’s east side, and how he plans to continue pushing for economic development and job creation in the community.
