YORBA LINDA, Calif. – Just months after he was deployed to Iraq in 2008, a Marine veteran now suspected in the deaths of four homeless men in Southern California sent his family a short, upbeat video greeting.
The video, which was mostly in Spanish, showed Itzcoatl Ocampo wishing his father a happy Father's Day and reading an excerpt from Dr. Seuss' "Green Eggs and Ham" to his then 10-year-old sister.
The former Marine's 17-year-old brother, Mixcoatl Ocampo, recalled how happy his family members were when they got the video in the mail that summer. They all gathered around the television in the living room to watch Itzcoatl Ocampo, who appeared in fatigues and talked against the backdrop of an American flag.
"We hadn't seen my brother since he got deployed," he said. "Dad saw the video, and when he first saw it he was thrilled."
According to friends and family, a much darker Ocampo returned home after he was discharged in 2010. His parents separated, and his father eventually became homeless.
Now, Ocampo's family is left trying to reconcile the smiling, slightly nervous-sounding soldier in the video greeting friends and family with the blankly staring man in the police mug shot accused of murder.
Orange County District Attorney Tony Rackauckas has scheduled a news conference for 11 a.m. Tuesday to announce charges against Itzcoatl Ocampo. The 23-year-old is expected to be charged with four counts of murder in the serial killings of four homeless men since late December.
He was arrested Jan. 13 after a locally known homeless man, John Berry, 64, was stabbed to death outside an Anaheim fast-food restaurant. Bystanders gave chase, and police made the arrest. Ocampo is being held in isolation at the central jail in Santa Ana for his own safety because of the notoriety of the case, according to Lt. Hal Brotheim, a spokesman with the Orange County Sheriff's Department.
Ocampo's father, 49-year-old Refugio Ocampo, said his son came back a changed man after serving in Iraq, expressing disillusionment and becoming ever darker as his family life frayed and he struggled to find his way as a civilian.
The father said he lost his job and home, and ended up living under a bridge before finding shelter in the cab of a broken-down big-rig he is helping repair.
Just days before his elder son's arrest, Itzcoatl Ocampo came to visit his father, warning him of the danger of being on the streets and showing him a picture of one of the victims.
"He was very worried about me," Refugio Ocampo told The Associated Press on Sunday. "I told him, 'Don't worry. I'm a survivor. Nothing will happen to me.'"
Itzcoatl Ocampo had been living with his mother, uncle, and younger brother and sister in a rented house on a horse ranch surrounded by the sprawling suburbs of Yorba Linda. At the humble home, his mother, who speaks little English, tearfully brought her son's Marine Corps dress uniform out of a closet and showed unit photos, citations and medals from his military service.
The son followed a friend into the Marine Corps right out of high school in 2006 instead of going to college as his father had hoped. Itzcoatl Ocampo was discharged in 2010 and returned home to find his family in disarray, his father said.
The same month, one of Itzcoatl Ocampo's friends, 22-year-old Cpl. Claudio Patino IV of Yorba Linda, was killed in combat operations in Helmand province, Afghanistan.
"Once he received the news, he was never the same," Mixcoatl Ocampo said. He said his brother visited Patino's grave twice a week.
Refugio and Mixcoatl both described a physical condition Itzcoatl suffered in which his hands shook and he suffered headaches. Medical treatments helped until he started drinking heavily, both said.
"He started drinking like crazy — too much, way too much," the father said.
A neighbor who is a Vietnam veteran and the father both tried to push Itzcoatl to get treatment at a Veterans hospital, but he refused. Refugio Ocampo said he wanted his son to get psychological treatment as well.
"He started talking about stuff that didn't make any sense, that the end of the world was going to happen," he said.
While Refugio Ocampo lives away from his family, they remain close. He saw his children every day, and his wife brings food to the parking lot where the truck is located in the city of Fullerton.
Refugio Ocampo, who said he was educated as a lawyer in Mexico, immigrated with his wife and Itzcoatl in 1988 and became a U.S. citizen. He described building a successful life in which he became a warehouse manager and bought a home in Yorba Linda. In the past few years he lost his job, ran out of savings, lost his house and separated from his wife.
Standing near the truck where he sleeps, Refugio Ocampo fought back tears as he described the changes he saw in his son in the year since returning home.
"Before, he had the initiative to do things, the desire. But after the military, he didn't have any of that," he said.
Refugio Ocampo said investigators came to him Friday night and showed him surveillance photos from a crime scene, but he did not recognize his son as the person in the images.
"If he did it, it wasn't right, obviously. But there's something wrong with him," he said.
In addition to Berry and McGillivray, Lloyd Middaugh, 42, was killed near a riverbed trail in Anaheim on Dec. 28; and Paulus Smit, 57, was found dead outside a Yorba Linda library on Dec. 30.
Authorities have provided no information on evidence against Ocampo, or a possible motive. But Anaheim Police Chief John Welter has said investigators are confident they have the man responsible for the string of murders.
