U.S. executes second man in two weeks, Kansas man who killed teenage girl, elderly woman

The United States on Thursday carried out its second federal execution this week, killing a Kansas man whose lawyers said dementia and was unfit to be executed, according to the Associated Press. 

Wesley Ira Purkey died by lethal injection at the Federal Correctional Complex in Terre Haute, Indiana, the wire service also reported.

Purkey was convicted of kidnapping and killing a 16-year-old girl before dismembering, burning and dumping her body in a septic pond. He also was convicted in a state court in Kansas after using a claw hammer to kill an 80-year-old woman who had polio.

Purkey reportedly expressed remorse right before he was executed, saying he deeply regretted "the pain and suffering" he caused surviving family members.

The Supreme Court voted 5-4 hours before the execution, allowing to occur.
