One DNA Profile - Tina Heins

On April 17, 1994, 20-year-old expectant mother Tina Heins was brutally murdered in her Jacksonville, Florida apartment. Police quickly set their sights on her 19-year-old brother-in-law, Chad Heins, who had been sleeping on the living room couch after a night out. Did police have the right guy in Chad? Or did tunnel vision allow the actual killer to slip through their fingers?
