A Salvadorian man facing two murder charges has been identified as an illegal immigrant.

Carlos Alejandro Reales-Dominguez has been arrested in connection with a series of brutal stabbings in Davis, California, according to KXTV.

Two of the attacks — which took place in city parks in late April — proved fatal, and the suspect is facing murder counts.

Another stabbing attack in May landed a homeless woman in an area hospital.

Reales-Dominguez is being charged with attempted murder in connection to that incident.

The suspect, a former University of California-Davis student, is being detained in the Yolo County jail.

Immigration and Customs Enforcement has filed a detainer on Reales-Dominguez — seeking notification should he ever be released from state custody.

An ICE official described Reales-Dominguez as a citizen of El Salvador who crossed the U.S.-Mexico border in Texas as an unaccompanied minor in April 2009.

Reales-Dominguez arrived at the border months after the inauguration of former President Barack Obama.

The suspect’s immigration case was closed “administratively” when he was transferred to the custody of a family member, an ICE source told KXTV.

Reales-Dominguez was detained on Wednesday and later arrested on Thursday, according to KCRA-TV.

Davis Police Chief Darren Pytel described the suspect as a serial killer in a news conference announcing his arrest.

“At this point, based on the information that we have and the definition of a serial killer, that would apply.”

Pytel indicated that the suspect was in possession of a large knife in a backpack when he was detained.

Reales-Dominguez made an initial court appearance on Friday, according to KXTV.
