• His initial death sentence was commuted to life imprisonment in 2013 when the Arizona Supreme Court ruled his intellectual disability made execution unconstitutional.

• Records show Grell lured his daughter with promises of Christmas lights, attempted to mislead witnesses and later confessed during a videotaped interview.
