Mexican drug lord Joaquín “El Chapo” Guzmán allegedly snuck into the United States twice last year while on the run from authorities following his dramatic prison escape.

The cartel boss’s daughter, Rosa Isela Guzmán Ortiz, said that shortly after “El Chapo” sat down for his Rolling Stone Magazine interview with Sean Penn, he escaped capture with the help of corrupt Mexican officials and evaded U.S. Border Patrol to sneak into California.

Guzmán Ortiz would not disclose the location in southern California where the drug lord was holed up, but said he came to visit her at her five-bedroom house which the drug kingpin bought for her and her four children.

“My dad deposited the money in a bank account with a lawyer and a while after he came to see the house, his house. He came twice,” Guzmán Ortiz told the Guardian.

The claims made by Chapo’s daughter cannot be independently verified and are likely to raise concerns among intelligence authorities in both the U.S. and Mexico.

Jacqueline Wasiluk, a Customs and Border Protection spokeswoman, told the Washington Post on Friday that the agency has “no information that substantiates the claims in news reports” about Guzmán.

Guzmán Ortiz said that she doesn’t know specifically how the drug lord arrived in the U.S. but that “El Chapo” allegedly paid off high-level Mexican officials.

“All I know is that my dad told his lawyer to deliver some checks to [a politician’s] campaign, and asked that he respect him,” she said.
