The US state of New Mexico will reopen a criminal probe into a ranch once owned by Jeffrey Epstein, following allegations that surfaced in justice department files on the convicted sex offender.

State prosecutors said they would seek full access to unredacted Epstein files relating to the Zorro Ranch, held by federal investigators in Washington DC.

They also pledged to work with a so-called Epstein truth commission set up this week in the state.

New Mexico shelved its initial investigation into the ranch in 2019 upon request from federal prosecutors in New York. Epstein, who died in a Manhattan jail in 2019, faced no charges in New Mexico.

Attorney General Raúl Torrez said on X that his office "will take a broad and comprehensive" look at the Zorro Ranch.
