Teen killed family to go to prom

A man was convicted of killing his father, stepmother and two stepsisters 17 years ago so he could attend some high school prom events.

Pelley was angry because his father had grounded him for stealing and would allow him to attend only the prom dance.

Prosecutors say Pelley shot his family members on the evening of the prom, disposed of the shotgun and shells, took a shower, put his clothes in the washer and left for the prom.
