More than half of Fresno County’s one million residents are Latino, and about 85-thousand are estimated to be undocumented. Like this woman we agreed to call “Gloria, a farm worker who came to the U.S. as a teenager 20 years ago. GLORIA: I left my family behind, my parents, my brothers, in Mexico, so I could come here to work. I’ve continued to work and never stopped. It’s heavy, heavy labor. JOANNE ELGART JENNINGS: Even though the work is hard, Gloria says, she has a good life with her three American-born kids. But she’s afraid she might lose it all. GLORIA: I fear that AT any moment I can be separated from my children. JOANNE ELGART JENNINGS: Gloria says many immigrants in Fresno are nervous about local law enforcement working with Federal Agents from Immigration, Customs and Enforcement – or “ICE. This highly publicized “ICE operation in February, resulting in 160 arrests in Los Angeles exacerbated those fears. It took place less than two weeks after President Trump signed his executive order broadening the types of individuals targeted for deportation. AIDA MACEDO: If you get deported by ICE, Child Protective Services cannot take custody of your children if you have somebody in charge.

They’re afraid to be even close to a local law enforcement jail or place or anything like that.

Fresno County Sheriff Margaret Mims says it’s one way she’s cooperating with Immigration and Customs Enforcement. SHERIFF MIMS: So if they state a country other than the United States, that’s where ICE will take a look and determine their legality in the country. JOANNE ELGART JENNINGS: ICE typically makes “detainer requests — asking local law enforcement to hold inmates suspected of immigration violations for up to two days beyond their scheduled release date. But that practice has been successfully challenged in court. So, instead, Mims now gives ICE agents access to the county jail’s database of bookings and criminal histories and allows ICE agents to interview inmates. MARGARET MIMS: At one time, all sheriffs in California respected the detainers and complied. Now, no sheriffs in California comply with those detainers. So I had a meeting with our local ICE office. And I said, “Well let me make it as easy as possible. You come into our jail where you can do your work and it will prevent somebody violent or a serious criminal from being released. JOANNE ELGART JENNINGS: The jail informs all inmates of the procedure at booking. OFFICER: This is just notifying you that ICE will be looking at everybody’s records that comes in here, okay? MAN: Alright. JOANNE ELGART JENNINGS: Since Fresno started this in 2015, ICE has taken custody of more than 330 individuals right from the jail.
