A man accused of stabbing his wife to death in front of their three young children at their Chula Vista home four years ago, then fleeing to Mexico, pleaded not guilty Wednesday to charges that include murder. Francisco Uriarte, 41, was extradited to San Diego this week in connection with the March 29, 2020, killing of his 35-year-old wife, Natalia Uriarte, according to police. The couple’s children, 9-year-old twins and a 3-year-old, were present at the time, police said. Officers who responded to the couple’s Oxford Street apartment around 1:30 a.m. found Natalia Uriarte dead and her husband gone. Uriarte had been at large since his wife’s death until his arrest in Mexicali in May, according to Mexican federal authorities. Police have not disclosed the circumstances behind his capture. He was handed over to U.S. authorities at the Mexico City International Airport for his trip back to San Diego, Mexican officials said. In arguing to deny him bail, Deputy District Attorney Erin Casey said that in addition to being a danger to the community for the “brutal and violent” slaying, Uriarte also sent a voicemail to a witness in the case in which he threatened to kill that person. San Diego Superior Court Judge Rebecca Kanter agreed to keep Uriarte jailed without bail. He’s due back in court in December. Staff writer Alexandra Mendoza contributed to this report.
