A black man, Fredrick Demond Scott, 22, was charged with killing two middle-aged white males and is a suspect in shooting three more in less than a year. Scott threatened in 2014 to shoot innocent children in a school and “kill all white people,” according to court records.

A municipal court citation for harassment said Fredrick Demond Scott made the statement in January 2014 at an alternative school in Kansas City, The Kansas City Star reported.

Scott has been charged with the murder of Steven Gibbons, 57, and John Palmer, 54. On Tuesday, the charges were announced by Jackson County Prosecutor Jean Peters Baker. The prosecutor also named Scott as a suspect in the deaths of David Lenox, 67, Timothy S. Rice, 57, and Mike Darby, 61.

All five men were white and were killed by gunshots in surprise attacks as they were walking down streets and in parks. Four were shot in the head — three in the back of the head. One was shot in the back. All of the shootings were near Indian Creek Trail, an area very close to Scott’s home.

Scott’s mother said in an interview with The Star that he refused to get treatment for his paranoid schizophrenia but did not show any hatred toward white people. Scott was cited in Kansas City municipal court in 2013 for assault on his mother, accused of shoving her several times.

Scott’s mother jumped to her son’s defense and said, “As far as I know Fredrick never had a problem with white people. He would do odd jobs for people and some of those people were white men.”

Scott told arresting detectives that he was extremely angry about the 2015 shooting death of his brother, Gerrod H. Woods, 23. Woods was fatally shot on December 14, 2015 during an apparent robbery near East 73rd and Wabash Avenue. The man who was convicted of that murder, Jimmie Verge, was sentenced to 45 years in prison, and is white. No racial motives were found in that shooting.
