The “probability is strong” that the human remains found in a Florida park on Wednesday belong to Brian Laundrie, a representative for the family said Wednesday night.

A backpack and a notebook belonging to Laundrie were also discovered in the park Wednesday on the same day Laundrie’s parents, Chris and Roberta, showed up to help search for their fugitive son.

Bertolino told Cuomo that he reached out to North Port police on Tuesday night to give them a heads up that the parents intended to help search the next morning.

Bertolino said Wednesday night that Brian’s parents are “heartbroken” over Wednesday’s developments
