Diane Zamora

Diane Michelle Zamora (born January 21, 1978), is a former United States Naval Academy midshipman who is serving a life sentence for the December 4, 1995, murder of Adrianne Jones, a girl Zamora believed was a romantic rival for her boyfriend, David Graham..

2007 interview
Zamora was interviewed by Stone Phillips on Dateline in a show broadcast in April, 2007. Her appeals were exhausted, and with her lawyer's permission she took a polygraph test administered by Dateline. Her story was now that Graham and she were breaking up, and that Graham was using the murder to “tie her to him”. She noted that she obstructed justice by cleaning the car afterwards and was an accessory after the fact; however, Zamora pointed out that the jury had convicted her of intending to kill Jones, which she denied. When she took the Dateline polygraph, the administrator repeatedly told her to stop her exaggerated breathing, a counter-measure for polygraph tests. Dateline’s polygraph administrator said he believed he had enough to actually say Zamora failed the crucial question on whether she had intended to kill Jones. Two other independent polygraph administrators, who were not at the test, were contacted by Dateline and asked to review the results said that they could offer no opinion due to counter-measures. Zamora responded to Phillips that she was nervous and hyperventilating despite being told all the questions in advance and reviewing them with the administrator before the test.

In popular culture
Zamora's case became the subject of a 1997 made-for-television movie called Swearing Allegiance (Love's Deadly Triangle: The Texas Cadet Murder). The movie tells the story of the murder of Adrianne Jones. The character of Diane Zamora was played by Holly Marie Combs.
