'20/20' INVESTIGATES A MYSTERIOUS BRUTAL MURDER AND THE BIZARRE HOME RENOVATION THAT MAY HAVE BEEN THE MOTIVE

Program Includes Exclusive Interviews With the Victim's Son and Ex-Husband

'20/20' Airs on Friday, Feb. 23 (9:01-11:00 p.m. EST), on ABC, Next Day on Hulu

When Shanti Cooper-Tronnes, a beloved mom and successful businesswoman, is found dead in the Florida home she shared with her husband, David Tronnes, police suspected it was a robbery gone wrong. Why else would her $15,000 diamond ring be missing? When investigators dismiss that theory, they turn their attention to a home renovation that the couple had undertaken, which was to be profiled on the A&E show "Zombie House Flipping." In a new episode, "20/20" co-anchor Deborah Roberts investigates the brutal murder and the bizarre home renovation that may have been the motive and details what investigators say was a secret that David Tronnes was keeping from everyone. The episode also profiles Shanti Cooper Tronnes' son, now age 14, who courageously fought for justice for his mother.

The two-hour program includes the first post-trial exclusive interviews with Jackson Cooper, Shanti's son, and Jim Cooper, Shanti's ex-husband. The episode also includes exclusive interviews with Detectives Teresa Sprague and Barbara Sharp, who doggedly spearheaded the fight for justice for Shanti; Michael Smith, assistant state attorney; Will Jay, prosecutor; and Dana Duran and Melissa Brzezinski, Shanti's close friends. Additional interviews include Ryan Vescio, former prosecutor; Jeff Dow, Shanti's step-father; Keith Ori, host of "Zombie House Flipping"; and additional friends of the victim. "20/20" airs on Friday, Feb. 23 (9:01-11:00 p.m. EST), on ABC, next day on Hulu.
