The wife of fugitive Mexican Sinaloa Cartel boss Joaquin Guzman, alias “El Chapo,” gave birth to twins at a hospital in Los Angeles County, California.

The Los Angeles Times reported Tuesday that Emma Coronel, a former beauty queen, crossed the border into California in mid-July and gave birth to daughters on August 15 at a hospital in Lancaster before returning to Mexico.

U.S. authorities tracked Coronel, who holds U.S. citizenship, as she traveled from Mexico to the United States and back. She has no pending criminal charges against her, however, and was not arrested.

Coronel is believed to be the third wife of Guzman, who is one of the world’s most wanted criminals and has been on the run since escaping from a Mexican jail in 2001. The couple were married in an elaborate ceremony in 2007 in the north-central state of Durango, on the day of her 18th birthday.

On the birth certificates of the twins, Coronel is named as the mother, but the space for father was left blank.
