On Friday evening, April 13, 2012, Brittany Killgore, 22, left her apartment near Camp Pendleton to go out on a San Diego dinner cruise with a man she barely knew.

Brittany had recently filed for divorce from her husband of two years, Marine Lance Corporal Cory Killgore. He was deployed to Afghanistan. She found herself alone with no job, so she decided to move back with her parents.  On the afternoon of Friday the 13th, she was packing when 45-year-old Marine Staff Sergeant Louis Perez came knocking on her door to ask her to go on this cruise with him. Brittany would never be seen again.
