Police seized knife sharpener from O.C. slaying suspect's bedroom Authorities seized a Life Magazine book titled "The Most Notorious Crimes in American History" and a knife sharpener from serial killing suspect Itzcoatl Ocampo's Yorba Linda home the day after he was arrested in the stabbing deaths of four Orange County homeless men, according to court documents. Ocampo, 23, is charged with four counts of special circumstances murder and is eligible for the death penalty. Orange County Dist. Tony Rackauckas said at a news conference last week that Ocampo stalked his victims and had more attacks planned. In a search warrant filed Friday, investigators said they found a Farberware knife sharpener in Ocampo's bedroom and various pieces of dark clothing, including five black long-sleeved shirts and two black fleece caps. Meanwhile, dramatic details emerged Wednesday about the scene and subsequent chase that started behind a Carl's Jr. when the fourth victim was killed and Ocampo was apprehended. Donald Hopkins, 32, a warehouse forklift operator and married father of two, was inside a nearby CVS when a man ran into the store screaming for help. Hopkins said he has no military or law enforcement experience but still ran toward the scene. I wish I could explain it, but I can't. I just reacted," he said. I didn't even think twice. He said he had "tunnel vision" on the killer, whose back was to Hopkins. Hopkins started yelling for the attacker to stop. When Hopkins was about 15 feet away, the killer turned and saw him, then sprinted across the parking lot. Hopkins ran after him. "I never looked back," Hopkins said Wednesday. He recalled that his hands were shaking as he tried to call 911; he finally had to slow to a jog to complete the call. He saw the killer shed a sweatshirt and gloves. When police arrived minutes later, Hopkins was able to point them in the direction the attacker ran. Officials and some residents returned to the shopping center Wednesday to honor Hopkins. He was given a $5,000 check and a plaque from the Assn. of Orange County Deputy Sheriffs for his role in the arrest of a suspect. That group and the Anaheim Police Assn. also donated a combined $5,000 to Mercy House, which provides support services for the homeless. "It's crazy," Hopkins said, after accepting the reward. It's a lot to take in. I'm just happy we were able to catch him. He said that while he was running, he was fearful that he could be stabbed. "But it happened so quickly I didn't really have time to think," he said. Hopkins said his family thinks "the world of me right now." He is seeking counseling for what he saw, as the scene is "stuck on repeat" in his head. "I feel like I was watching a movie," he said. In the search warrant obtained by the Los Angeles Times, Anaheim Police Det. Mark Lillemoen said Hopkins chased the attacker to a gate on the west side of Friendly Village, a mobile home park next to the shopping center. "Hopkins did not go in the gate because he feared Ocampo would attempt to stab him," Lillemoen wrote. In the search warrant, Lillemoen justified taking the clothing from Ocampo's room. Because each of the victims was stabbed, he wrote, "I believe there may be items containing remnants or stains of blood on them." He also summarized each of the stabbings. The first occurred on Dec. 20 in a Placentia shopping center, where James McGillivray, 53, was stabbed "numerous times as he was sleeping on the side of the business," according to the document. Lillemoen said he reviewed surveillance video that shows the killer stabbing the victim with "a large, fixed-blade knife." At a news conference last week, Rackauckas identified the suspected weapon as a single-edged, 7-inch Ka-Bar Bull Dozier knife. Police found the second victim, later identified as Lloyd "Jim" Middaugh, 42, on Dec. 28 on the Santa Ana River trail. According to the affidavit, he too was sleeping at the time of the attack. Lillemoen obtained surveillance video from a Bank of America branch in Yorba Linda, near where Paulus Smit, 57, was stabbed to death on Dec. 30. In the video, a man dressed in a dark beanie, a dark long-sleeved shirt, blue jeans, black shoes and dark gloves is seen walking in the direction of the crime scene. He also details the Jan. 13 stabbing of John Barry, 64, the attack that led to the suspect's capture. Investigators also swabbed Ocampo's shower drain and bathroom sink for DNA. On Jan. 14, they obtained a cheek swab from Ocampo. Among other items taken as evidence from Ocampo's home were white T-shirts, some ripped and torn; blue and black jeans; black dress pants; a toothbrush; Caterpillar boots; a BB gun; and a computer.
