One of New Jersey's most notorious cold cases is getting a new life.

The New Jersey Supreme Court has taken the rare step of ordering a rehearing in the 2016 murder conviction of Michelle Lodzinski.

In May, the court split 3-3 but rejected Lodzinski's appeal of her conviction for killing her 5-year-old son Timothy Wiltsey in 1991. On Wednesday, the Supreme Court conceded it made a procedural mistake in its ruling.

A rehearing on the matter is scheduled for later this month.

Lodzinski claimed her son disappeared while they were at a carnival, but gave varying accounts to investigators about what happened. Prosecutors argued a blanket found with the boy's body the following year tied Lodzinski to his death.
