LEE COUNTY, Fla. (CNN) - A fugitive from Puerto Rico who has been on the run for almost 40 years is now back in custody. Jorge Milla-Valdes escaped from a Puerto Rican prison in 1987. Authorities believed he was living under an assumed name, Luis Aguirre, in Lee County, Florida.

Jorge Milla-Valdes was serving a robbery sentence when he escaped prison in 1987, according to the Lee County Sheriff’s Office in Florida. He moved to Florida and began living under the name Luis Aguirre with a different date of birth, as law enforcement said he racked up more criminal charges.
