Police have named the white man who killed three black people at a store in Florida in a racially motivated shooting on Saturday as 21-year-old Ryan Palmeter.
Palmerter shot one of his victims as she sat in her car outside the Dollar General store store in Jacksonville.
He shot another just after he entered the store; and shot the third minutes later, Jacksonville’s sheriff said.
He murdered his victims with a AR-15 semi-automatic rifle and a Glock handgun bought legally.
It was also revealed the Palmeter was involuntarily committed for a mental health examination in 2017.
After the shooting racist manifestos were found at his his home which were addressed to his family, federal law enforcement and the media, in which he told of his hatred of black people, the sheriff said.
The force also identified those were were killed in the incident at the Dollar General store.
Sheriff TK Waters said Angela Michelle Carr was shot in her car; store employee AJ Laguerre was shot as he tried to flee; and customer Jerrald Gallion was shot as he entered the store, which is in a predominantly black neighbourhood.
Mr Palmeter lived with his parents in neighbouring Clay County and had texted his father during the shooting and told him to break into his room, Mr Waters said.
The father then found a suicide note, a will, and writings that Mr Waters has described as racist.
Mr Waters said the guns were purchased in April and in June, with the dealers following all the laws and procedures, including background checks.
Because Palmeter was released after his mental health examination, that would not have shown up on his background checks.
“Therein lies the difficulty. When a person grabs hold of a gun with hateful intentions, it is very difficult to stop that from happening,” the sheriff said.
On Saturday shortly before 1pm local time, Palmeter parked at Edward Waters University, an historically black college less than a mile from the Dollar General.
The sheriff said he posted a TikTok video of himself donning a bullet-resistant vest and gloves.
It was at about this time that a university security guard spotted Mr Palmeter and parked near him.
He then drove off and the security guard flagged down a Jacksonville sheriff’s officer who was about to send out an alert to other officers when the shooting began at the store.
During the shooting he entered the store’s office and texted his father, telling him to use a screwdriver to break into his room.
There, his father found a suicide note and a will.
“The manifesto is, quite frankly, the diary of a mad man,” Mr Waters said.
“He was just completely irrational. But with irrational thoughts, he knew what he was doing. He was 100% lucid.”
Eleven minutes after the shooting began, and as police entered the store, Mr Palmeter killed himself.
Elected officials said racist attacks such as Saturday’s have been encouraged by political rhetoric targeting “wokeness”.
They also claimed they were inspired by policies from the Republican-led state government headed by Florida governor Ron DeSantis, including one taking aim at the teaching of black history in Florida.
State representative Angie Nixon, a Jacksonville Democrat, said: “We must be clear, it was not just racially motivated, it was racist violence that has been perpetuated by rhetoric and policies designed to attack black people, period.
“We cannot sit idly by as our history is being erased, as our lives are being devalued, as wokeness is being attacked,” Ms Nixon said.
“Because let’s be clear – that is red meat to a base of voters.”
