CHEYENNE, Wyo. (AP) — An undated letter from the mother of the man who killed Gabby Petito to her son will be allowed as possible evidence in a lawsuit Petito’s parents have filed against the parents of her killer.

A judge in Florida sided with the Petito family in admitting the letter Wednesday.

The letter from Roberta Laundrie to her son, Brian Laundrie, says she would “dispose of a body” for him because she loved him so.

Roberta Laundrie says she wrote the letter a few months before her son killed Petito.

The Petito family says the letter suggests she knew of the killing before Petito's body was found.
