He did not give further information on what or how many items were found.
Bertolino said police are now conducting a more thorough investigation of that area.

Almost two months ago, Petito, 22, disappeared while she and Laundrie, 23, were on a road trip through the western United States, documenting their travels on social media.
Laundrie returned home to North Point, Florida, where they lived with her parents, without Petito on September 1.
After being unable to contact her, Petito's family reported her missing 10 days later.
Laundrie refused to cooperate with the investigation into his whereabouts, and soon after, he, too, disappeared, with his family telling investigators they believed he had gone to a nearby nature reserve.
Petito's remains were found in a national forest in Wyoming on Sept. 19 near where the couple had last been seen together.
Teton County Medical Examiner Dr. Brent Blue has ruled that he died from strangulation.
Laundrie has not been explicitly linked to Petito's murder, but he is the subject of a federal arrest warrant for unauthorized use of someone else's debit card in the days after Petito last spoke to his family.
