Jonathan Corwin, the Marine whose wife Erin Corwin was murdered by her lover in 2014, is speaking out for the first time on television in a Dateline network exclusive special, “The Last Day.”

Opening up about the June day that Erin, 19, disappeared after leaving their home at the Twentynine Palms Marine base in California, Jonathan speaks somberly as he details what would be their final goodbye.

“She had woke[sic] up and gotten dressed and gave me a kiss goodbye,” he reveals in the exclusive clip.

“[She] said, ‘Hey, I’m heading out for the day and I love you,’ ” he recalls. “I told her, ‘I love you too,’ and I rolled back over and went to sleep.”

Erin Corwin’s lover, Christopher Lee, was found guilty of Erin’s murder on Nov. 3. On Tuesday he was sentenced to life in prison without the possibility of parole, according to multiple reports.

Lee, a former Twentynine Palms Marine, confessed in court to strangling Erin and throwing her body down a 140-foot desert mineshaft.

Erin, who was allegedly pregnant at the time of her death (Corwin had told friends and loved ones that she was expecting, but medical examiners could not confirm it) was missing for nearly two months before her remains were found in the mineshaft near Joshua Tree National Park.

Lee’s switch to a guilty plea came as a surprise during his trial. He abruptly recanted his not-guilty plea and announced that he acted on impulse in killing his neighbor Erin. The 26-year-old claimed that he was partially motivated by his suspicion that Erin had molested his 6-year-old daughter.

In a statement at his sentencing, Lee asserted that he killed Erin in a rage and confessed to “save his humanity.”

Dateline‘s full coverage of Erin’s murder, and interviews with Jonathan, her mother and more, airs Friday at 9 p.m on NBC.
