A woman found dead in her Florida bedroom creates an impossible whodunit: her husband Bill and adult son Kevin each accuse the other of murder in dueling 911 calls. Blood evidence, conflicting stories, and a shocking acquittal leave Diane Kine's true killer unknown—but one man is definitely lying. Kevin Kine was convicted of murdering his mother based on his blood found at the crime scene and broken glasses in her bedroom, but won acquittal at retrial when the defense aggressively challenged Bill's credibility and highlighted the $750,000 insurance payout motive.
