Feb. 18: 'While They Were Sleeping'

As the full moon rose over the Sierra Nevada Mountains, someone broke into the home of Ben and Melissa Oxley and shot 36-year-old Ben in the head, as he slept next to his wife.

Dateline NBC's Keith Morrison reports While They Were Sleeping  on Sunday, February 10th, at 8pm/7c.
