Police: Buffalo gunman aimed to keep killing if he got away

Buffalo's police commissioner says the white gunman accused of a racist rampage at a supermarket planned to keep killing people if he had escaped the scene.

Police Commissioner Joseph Gramaglia spoke to CNN on Monday, while authorities investigated the massacre of 10 Black shoppers and workers as a potential federal hate crime or act of domestic terrorism.

Gramiglia says the gunman even talked about shooting up another store.

The accused gunman, 18-year-old Payton Gendron, ultimately surrendered to police who confronted him in the supermarket's vestibule.

He has been charged with murder.

The victims of Saturday's racially motivated shooting in Buffalo, New York, include retired police officer Aaron Salter.

Officials credit the security guard at Tops Friendly Market with saving lives.

Katherine Massey was also killed while shopping.

Her sister calls her ``a beautiful soul.''

Ruth Whitfield was getting groceries after visiting her husband at a nursing home.

Her son calls her a loving mother with a strong religious faith.

Zaire Goodman is the son of a staffer to state Sen. Tim Kennedy.

Goodman is recovering after being shot in the neck.

In total, 13 people were shot, 10 fatally.

Authorities say authorities the gunman went to the store with the ``express purpose'' of killing Black people.
