The white man who shot and killed three black people at the Dollar General store in Jacksonville, Florida on Saturday was a 21-year-old who bought his guns legally and had no criminal history.
According to Sheriff T.K. Waters in a news conference on Sunday, the shooter Ryan Christopher Palmeter, who lived with his parents in a suburb of Jacksonville died of a self-inflicted gunshot wound.
Waters has said the shooting was racially motivated. Authorities say the shooter left behind several manifestos for the media, his parents and law enforcement detailing his hatred for Black people, Reuters reports.
"There was no criminal record, nothing,” Waters said, adding the only thing on file was a domestic violence call with his brother. "There were no red flags."
However, the sheriff said Palmeter in 2017 was briefly held under a state law called the Baker Act, which states a person can be "taken to a receiving facility for involuntary examination" during a mental health crisis.
"We must refuse to live in a country where Black families going to the store or Black students going to school live in fear of being gunned down because of the color of their skin," Biden said.
The Justice Department is investigating the shooting as a hate crime and an "act of racially motivated violent extremism," U.S. Attorney General Merrick Garland said in a statement. Garland said the shooting would be investigated as a hate crime.
Waters said the suspect was caught on video shooting Angela Michelle Carr, a 52-year-old woman, in her car outside the Dollar General, a U.S. discount chain. He then entered the store where he shot and killed 19-year-old Anolt Joseph "AJ" Laguerre Jr and Jerrald De'Shaun Gallion, 29.
Palmeter wore a tactical vest and his face was covered by a mask, Walters said. He carried a handgun and an "AR-15 style" rifle, with swastikas on it, police said, referring to a lightweight semi-automatic long gun often used in mass shootings.
Authorities said he was spotted trying to enter a local historically Black college, Edward Waters University, on Saturday before heading to the Dollar General store.
Palmeter had refused to identify himself to a campus officer and was turned away. "It was later determined that the individual would be involved in a shooting near EWU campus," the university said.
Florida Governor Ron DeSantis said on Sunday the state would work with the school to ensure it has adequate security following Saturday's shooting.
DeSantis, a Republican presidential candidate, has been sharply criticized by Black leaders for what they say is his government's attack on Black history.
In January, Florida banned an Advanced Placement course on African-American history from being offered to high school students. In July, the state changed how history is taught in schools.
DeSantis was booed when he began to speak at a prayer vigil for the three victims on Sunday.
Jacksonville city councilwoman Ju'Coby Pittman, a Democrat who represents the area where the shooting took place, chastised the crowd and told them the governor was there to help.
DeSantis then told the crowd the gunman was "a major-league scumbag" and said in Florida "we're not going to let people be targeted based on their race."
