Officials reported that 206 criminally charged illegal aliens were released from the custody of jails after an immigration detainer had been issued.
The other California locations where detainer requests were declined were: the Santa Rita jail in Alameda County; Madera County Department of Corrections; the Anaheim city jail in Orange County; the Sacramento County jail; the Santa Barbara County jail; and the Santa Clara County main jail.
The report lays out 206 declined "detainers" that were registered in Immigrations and Customs Enforcement databases for the week of January 28 to February 3.
Such cities and counties, commonly described as "sanctuary jurisdictions", may not cooperate with the detainer requests for a variety of reasons.
In a fact sheet sent by the DHS in connection with the detainer report, ICE explains that the data is based on information it compiles after a request is declined.
In President Donald Trump's executive order, entitled "Enhancing Public Safety in the Interior of the United States", which he signed on January 25, he declared that, "Interior enforcement of our Nation's immigration laws is critically important to the national security and public safety of the United States". "Texas will act to put an end to sanctuary policies that put the lives of our citizens at risk".
The list shows that cities and towns are not helping immigration authorities deport potentially serious criminals, including people arrested on suspicion of or convicted of drunken driving, aggravated assault and homicide, Homeland Security officials said. Some say that cooperating can undermine local trust in the police if immigrants are afraid that reporting a crime will result in their own deportation.
The suspects in those jails had convictions for domestic violence, burglary and forgery, among other crimes.
After almost declining an ICE detainer issued for a man accused of molesting a child, Hernandez said she would consider expanding her policy to include crimes committed against children and elderly.
A detainer becomes declined when law enforcement agencies do not honor ICE's detainer, and continue to release the "criminal alien" back into the public, according to DHS.
The Trump administration on Monday opened up its first line of attack on so-called sanctuary cities, naming jurisdictions that decline to detain immigrants who could be subject to deportation. Hundreds of local police agencies depend on hundreds of millions of dollars in grants from Homeland Security and the Department of Justice.
"This is an effort for us to be transparent with regards to how we conduct our enforcement operations and the public safety from those agencies that don't cooperate with those enforcement efforts", said a senior DHS official in a briefing call with reporters.
