- The suspect in the Buffalo mass shooting had plans to continue his deadly rampage, police said.
- "It appeared that his plans were to drive out of here" and continue "looking to shoot more Black people," the city's police chief told "Good Morning America."
- The Justice Department is investigating the shooting as "an act of racially-motivated violent extremism."
The Buffalo, New York, mass shooting suspect had plans to continue his deadly rampage and target more Black people, the city's police commissioner said on Monday.
The suspect, identified by police as an 18-year-old white man, opened fire on Saturday at the Tops supermarket in a predominantly Black neighborhood, killing 10 and wounding three others. Of the 13 shot, 11 were Black, and two were white, police said.
Authorities have described the attack as a "racially motivated hate crime," and the US Justice Department is investigating it as a hate crime and "an act of racially motivated violent extremism."
Buffalo Police commissioner Joseph Gramaglia told ABC's "Good Morning America" on Monday that "it appeared" that the shooting suspect had plans "to drive out of here and then continue driving down Jefferson Avenue looking to shoot more Black people… and possibly even go to another store location."
Gramaglia also told CNN on Monday that authorities discovered "some documentation" outlining the suspect's plans for possibly another shooting at "another large superstore."
"There was evidence that was uncovered that he had plans, had he gotten out of here, to continue his rampage and continue shooting people," Gramaglia told CNN.
The shooting suspect was arrested and charged with first-degree murder after the mass shooting. He has pleaded not guilty.
Federal officials said that a manifesto that appears to belong to the suspect mentioned plans to kill Black people and referenced the so-called replacement theory, a white supremacist conspiracy theory that believes white people are being replaced by people of color.
