Facts of the Crime:

Dunkle's sanity has been an issue since he was arrested in 1986 for the Peninsula murders of 15-year-old John Davies and 12-year-old Lance Turner. Dunkle eventually confessed to killing Davies in 1981, Turner in 1984 and a 12-year-old boy in Sacramento in 1985.

Dunkle was sentenced to death in San Mateo County on July 2, 1990.
