SANTA BARBARA, Calif. -

The murder of a child in Santa Barbara 35 years ago sent shock waves throughout the community. Now the family's tragedy is getting national attention.

Discovery Channel will air the story behind 7-year old Javier Angel's death in December, 1978.

Javier was found strangled and stuffed in trash bags in a house next door to his parent's Santa Barbara market.

Julia Diaz, 22, was convicted of the murder and sentenced to 25 years to life in prison.
