SANTA ANA (AP) — Eder Herrera lost his mother and brother to a gruesome stabbing and spent three months in jail as the prime suspect.Even after his best friend from high school confessed to the crimes and four other killings in Southern California — before committing suicide in jail — authorities say Herrera is still under suspicion in the deaths of his family members.Now, Herrera, 26, is trying to clear his name, filing a federal civil rights lawsuit against police for wrongful imprisonment and fighting deportation proceedings to Mexico, a country he hardly knows, that were spawned by his arrest.“I’m trying to get over this situation, but they keep pulling me back,” Herrera said.Herrera will make his case Friday in Orange County Superior Court for authorities to return his belongings, including a laptop computer his mother gave him and family videos that police seized. In federal court, he is asking for access to police evidence and unspecified monetary damages.Prosecutors say while Herrera isn’t charged, he may have been involved in the murders in some capacity and police are still investigating. An attorney representing the police would not comment on the wrongful arrest allegations or the evidence.“There was significant circumstantial evidence that led us to believe he was involved initially, and that evidence still exists,” said Brea police Chief Jack Conklin, who also declined to discuss the nature of the evidence his investigators have.Authorities say Herrera’s best friend, Itzcoatl Ocampo, decided to kill him and his family after the two had a falling out.
