Police Interrogations: Can Police Unravel a Mother's Death?

Huntington Beach, CA, September 17, 2006

The body of Barbara Mullinex was found covered with stab wounds in the soggy remains of a cardboard box in Newport Harbor. Her 17-year-old daughter, Rachael, and Rachel's fiancé, Ian Allen, fled the state right after the murder, but were soon found and brought in for questioning.

Although Rachel Mullinex continued to say that her boyfriend acted alone, both she and Allen were found guilty of murder, and sentenced to 25 years to life in prison.
