That quote comes from a police detective who interviewed Itzcoatl Ocampo after he was arrested following the stabbing death Jan. 13 of the fourth homeless man outside a Carl's Jr. restaurant in Anaheim.
In court documents, the detective told the grand jury that Ocampo said he was disappointed when he did not see any combat during a six-month tour of duty, because he became a truck driver instead of a killer.
"He felt in order to become a real Marine, he needed to kill," Detective Daron Wyatt told the grand jury.
Ocampo told Wyatt that he had planned to continue killing people and hoped to build a kill list with 16 names before he was finished, according to the transcript.
Ocampo was charged in February with the murders of four homeless men in December and January, and with murdering Raquel Estrada, 53, and her son, Juan Herrera, 34, in their Yorba Linda home. Estrada's youngest son initially was charged with the attack.
Ocampo has pleaded not guilty to all charges. His trial is scheduled for Sept. 10.
