BONNE TERRE, Missouri -?White supremacist serial killer Joseph Paul Franklin has been put to death in Missouri. It was the state's first execution in nearly three years.

The 63-year-old Franklin targeted blacks and Jews in a cross-country killing spree from 1977 to 1980. He was executed Wednesday at the state prison in Bonne Terre for killing Gerald Gordon in a sniper shooting outside a suburban St. Louis synagogue in 1977.

Franklin was convicted of seven other murders across the country and claimed responsibility for up to 20 overall. The Missouri case was the only one that brought a death sentence.

The execution was the first in Missouri using a single drug, pentobarbital.

Franklin's fate was sealed early Wednesday when the US Supreme Court upheld a federal appeals court decision overturning stays granted Tuesday.
