Etan Patz murder heads to 3rd trial

The case has remained one of the most notorious unsolved mysteries in American history, leading to major changes in how missing children cases are handled.

Hernandez was convicted in a second trial in 2017 after his first trial ended in a hung jury, but his legal team has continued to challenge the verdict.

The judge's decision on Friday ensures that the long-running legal saga will continue as prosecutors seek to maintain the conviction.

Etan Patz was the first missing child to be featured on a milk carton, a symbol of the national effort to find missing youth.
