The body was found on July 8, but the Will County Coroner did not identify her as Martha 'Tica' Sanchez until Thursday. Sanchez had been reported missing from Chicago's Portage Park neighborhood since July 4.
Police said that a joint investigation by the Illinois State Police, Will County State's Attorney's Office and Blue Island Police Department resulted in the arrests of two men in connection with Sanchez's death.
Jonathan "Jon Jon" Rodriguez, 29, of Blue Island and Esteban "Steve" Rodriguez, 27, of Wilmington have both been charged with felony concealment of death and felony intimidation. Police said Esteban was armed with a handgun when taken into custody.
Both men are being held on $1 million bond, police said. The investigation is ongoing.
