Local law enforcement today released the name of the white gunman who shot and killed three African-Americans at a Dollar General store in Jacksonville, Florida, yesterday, Saturday, identifying the gunman as Ryan Christopher Palmeter, 21.

Authorities said the shooting was racially motivated, saying the young man had written “several manifestos” for the media, his parents and law enforcement detailing his hatred of black people.

The suspect had no criminal record and had legally purchased the guns he used in the shootings, said Jacksonville Sheriff T.K. Waters today at a press conference.

“There was no criminal record, nothing,” he said, adding that all he had on file was a domestic violence call with his brother. “There was no warning sign,” he said.
