Lawyer Hernan Fernandez, who represents Weisfeiler's sister, said progress has been made by police, but declined to provide more details. Fernandez maintains there is evidence to suggest the missing Russian-born mathematician was killed intentionally.
Two U.S. congressmen are asking Chile's new president to continue the investigation into the disappearance of a Penn State University professor.
Pinera has promised that his government will respect human rights, and Chile's judicial system has demonstrated considerable independence from the executive branch.
Boris Weisfeiler was 43 when he was arrested by a military patrol while camping near Parral, 210 miles south of the capital of Santiago. He was close to Colonia Dignidad, a German enclave used as a torture and detention center by the secret police of dictator Gen. Augusto Pinochet, according to judiciary investigations.
He is one of more than 3,000 people who vanished after being arrested during Pinochet's military dictatorship.
