The girls' bodies were found in a forest preserve in far north suburban Zion seven years ago. Both were stabbed to death.
Laura's father, Jerry Hobbs, was originally charged and held in jail for 5 years until DNA evidence showed he did not commit the crime. The DNA matched that of Jorge Torrez, a former Zion resident who is in prison in Virginia.
On Tuesday, Torrez was charged with first-degree murder.
