The United States has executed Wesley Purkey in its second federal execution this week after a 17-year hiatus. Purkey, 68, was executed via lethal injection on Thursday morning in Terre Haute, Ind.
The Supreme Court early Thursday denied appeals to stay Purkey's execution, clearing the way for it to proceed.
Purkey, who was on death row at the U.S. Penitentiary in Terre Haute, was convicted of the 1998 kidnapping and killing of 16-year-old Jennifer Long.
