A nearly 11-hour standoff with a 44-year-old domestic violence suspect in San Marcos ended with his arrest Monday, authorities said. Detectives with the Sheriff’s Office were following up on a domestic violence report at a condominium on Flatiron Way near North Fork Lane West at 10 a.m. Monday when a man inside refused to speak with them and threatened to hurt himself and deputies, officials said. The Sheriff’s Special Enforcement Detail, Crisis Negotiations Team and Psychiatric Emergency Response Team responded and tried to de-escalate the situation. Deputies contacted the man several times to try to get him to surrender, but he did not respond. As a precaution, deputies evacuated nearby condos in the complex. Around 9 p.m., Monday, the SWAT team used a chemical agent to enter the unit. The suspect was arrested and taken to a hospital to be evaluated, officials said. Deputies obtained a warrant and searched the home, seizing rifles and handguns. The man’s wife and children were provided resources designed for people affected by domestic violence. He was booked into Vista jail on suspicion of felony domestic violence, resisting an officer, disobeying a court order and a weapons possession charge, according to court records.
