A man already in federal custody awaiting sentencing on immigration charges has been charged with murder in a March killing in Frederick, authorities said Friday.

Jose Reyes Mejia-Varela, 21, was charged with the March 18 killing of Jacinta “Patty” Ayala, according to the Frederick police.


Mejia-Varela was in the custody of the U.S. Marshals Service awaiting sentencing on charges of illegally re-entering the country after having been deported as an aggravated felon, police said.

Following federal sentencing, a warrant will be issued for the murder charge, according to police.

Mejia-Varela was charged with first-degree murder and assault and armed robbery charges in connection with the Ayala murder.
