Christian Michael Longo (born January 23, 1974)[4][5] is a convicted murderer[6] who killed his wife and three children in Oregon in December 2001.

He left the hotel on January 7, 2002, and was captured six days later without incident in the small town of Tulum, Quintana Roo, about 80 miles (130 km) south of Cancún.

[12] Years later, Longo admitted to being a narcissist in a letter he wrote to a woman that was obtained by television station KATU-TV in Portland, Oregon.

He wrote that he eventually began "studying what a psychologist said I was and came to terms with it, almost totally agreeing that he was right... his conclusion was the narcissistic personality disorder which he called 'compensatory' – basically self-centeredness related to a damaged core sense of self.

[15] In 2011, Christian Longo founded Gifts of Anatomical Value from Everyone (GAVE), which advocates for death row prisoners being allowed to donate their organs.

However, Longo has countered that death row inmates interested in donating their organs could undergo intensive screening far ahead of their execution.
