BURNING BED AIRING ON "20/20 SATURDAY," JANUARY 10, 10 PM ON ABC

Who killed Lucy Johnson, shot in the head twice and left in a house set on fire? With no shortage of suspects including her ex-boyfriend and her fiancé, pregnant after just three weeks together and engaged after three months, "20/20" follows the twists and turns of this explosive whodunit story. Police focused on four men in her life, believing it was not a stranger since no locks in the house were forced. Even Lucy had an opinion about who might have wanted her dead, as her journal was read in court. The jury speaks out about the case and why they ruled the way they did. Jim Avila's report airs on "20/20 SATURDAY" on JANUARY 10 (10:00-11:00 p.m., ET) on the ABC Television Network. (OAD: 6/6/14)

"20/20" is anchored by Elizabeth Vargas and David Muir. David Sloan is the senior executive producer.
