Roderick Nunley

Missouri man faces execution for raping, killing 15-year-old

But a detective who helped break the case scoffed at the appeal Monday, saying Roderick Nunley should have been put to death long ago.

Nunley and a co-defendant were accused of kidnapping Ann Harrison as she waited for a school bus in Kansas City, then raping and killing the girl in 1989. If the courts don't step in, the 50-year-old Nunley will be lethally injected at 6 p.m. Tuesday and become the sixth inmate executed this year in Missouri.
