Police in San Antonio have arrested a man who was reportedly in the country illegally in connection to the murder of his elderly partner, KSAT first reported.

San Antonio police confirmed to KSAT that 26-year-old Alberto Rafael Ferrer Cabrera was arrested on Saturday in connection to the death of his 81-year-old partner.

The Bexar County Sheriff’s Office confirmed to Fox News Digital that Cabrera was in the country illegally and that he has a detainer on him from Immigration and Customs Enforcement.

According to court records obtained by KSAT, Cabrera claimed to have murdered his significant other.

The arrests are among thousands throughout the country since the Trump administration took office in January. Trump promised to launch a “historic” mass deportation operation. Officials have said they are prioritizing public safety threats but are also not excluding illegal immigrants who do not have criminal convictions or charges.

The administration has lifted a number of Biden-era restrictions on ICE agents, including limits on their ability to enter “sensitive” areas like churches or schools.

On Monday, Fox News Digital reported that the administration has ended Temporary Protected Status — which protects migrants from certain nations from deportation — for over 300,000 deportations. The Biden administration had extended TPS for a number of nationalities before leaving office, a move that makes it harder for ICE to deport them.
