Perillo's trip to death row began when she and two friends were picked up 
by Bob Skeens, 26, and Robert Banks, 30, while hitchhiking near Houston's 
Astrodome on Feb. 24, 1980. 

The three hitchhikers later robbed and killed Skeens and Banks, then went 
on the run for months. After a fight with accomplice James Michael Briddle 
in Colorado, Perillo turned herself in and gave police a 26-page statement 
about the crimes.
