The White Supremacist who murdered three people last year in a gun rampage outside two Jewish institutions will be put to death, a jury has ruled.

Frazier Glenn Cross (Miller), 74, admitted to shooting dead three people outside two Jewish centers in Kansas City last year, saying he wanted to kill Jews because they have “too much power”.

He was convicted of those murders as well as the attempted murder of three other people. 

The Passover eve shootings killed William Corporon, 69, and Corporon's 14-year-old grandson, Reat Griffin Underwood, at the Jewish Community Center in Overland Park; and Terri LaManno, 53, at the nearby Village Shalom retirement center.

Despite his anti-Semitic motives none of his victims were in fact Jews - a fact he said he regretted in an interview after the event.

Although he admitted to killing the three people, he pleaded not guilty, saying it was his duty to stop genocide against the white race.

He was representing himself after firing his state-appointed attorneys.
