Iraq War veteran charged with stabbing six to death said that he did so because 'he had a killer gene' and largely targeted homeless men because they were 'available'

A former Marine charged with the gory stabbing deaths of six people in California told investigators he targeted homeless people in part because they were vulnerable, and that he believes he has a 'killer gene'.

Itzcoatl Ocampo, a 23-year-old Iraq War veteran, was initially arrested for the stabbing deaths of four homeless men earlier this year.

Ocampo later confessed to two more murders - the October killings of his high school friend Eder Herrera's mother and brother in Yorba Linda.

The revelations come as Ocampo faces six felony counts of murder for allegedly stalking and stabbing his victims in killings authorities said were carried out with a roughly seven-inch military-style blade and that terrorized Orange County's homeless community.
