SANTA ANA, Calif., Feb. 3 (UPI) -- Itzcoatl Ocampo, accused of killing four homeless men, is suspected in the Yorba Linda, Calif., stabbing deaths of a woman and one of her sons, police said.
Anaheim Police Lt. Julian Harvey, who heads the task force investigating the homeless slayings, said authorities have found evidence that appears to link Ocampo to the October 2011 slayings of Raquel Estrada, 53, and Juan Herrera, 34, in their home, the Los Angeles Times reported Friday.
Ocampo was arrested Jan. 13 after he allegedly stabbed John Barry, the fourth homeless man to be killed in Southern California since Dec. 20.
"We've developed evidence that leads us to believe very strongly that Mr. Ocampo was involved in the double murders" of Estrada and Herrera, Harvey said.
Estrada's younger son, Eder Herrera, was arrested on suspicion of killing his mother and brother. He has pleaded not guilty and remains in custody.
"It does not mean Mr. Herrera is not involved," Harvey said. "Part of our investigation is to prove or disprove Mr. Herrera's involvement."
The slayings occurred less than a mile from Ocampo's home.
