The Story From Inside the Courtroom and Interviews with Key Players Airs on "20/20," Friday, July 12 at 10 p.m. on ABC

It has been the burning question in a murder case that has polarized the country - what exactly happened when teenager Trayvon Martin was shot dead after a fatal encounter with 28-year-old George Zimmerman? Was it murder or self-defense? The case comes to a close after a heated three week trial that presented the jury with two wildly different versions of events. From inside the courtroom, and interviews with key players, ABC News' Matt Gutman reports the latest and most in-depth information from the trial on "20/20? airing FRIDAY, JULY 12 (10:01-11:00 p.m., ET) on ABC. "20/20? is anchored by Elizabeth Vargas and David Muir.

Plus: Many are watching the trial of George Zimmerman, but perhaps none with more interest than Mindy Danaher. Her husband Kelly was shot and killed in Texas two years before Trayvon Martin. Like Zimmerman, Paul Rodriquez, the man who shot Kelly, claimed self defense under the Texas version of the Stand Your Ground law. David Muir interviews Mindy about the parallels between the two cases.

David Sloan is senior executive producer of "20/20? and John Green is the executive producer.
