Man Charged With Throwing Rocks At Police

An island resident was charged and arraigned in Nantucket District Court Monday morning for allegedly throwing rocks at police officers while they were conducting a traffic stop last month, and was later caught trespassing in a neighbor’s yard.
Roberto Carlos Chacon, 29, of Nantucket was arraigned on October 12th charges of assault & battery on a police officer, assault & battery with a dangerous weapon, and trespassing. He had not-guilty pleas entered on his behalf and he was ordered to return to court January 12th, 2026 for a pretrial hearing.
These new charges also violated the probation he was serving on an April 17th, 2023 charge of operating a motor vehicle under the influence of alcohol, and a probation violation hearing was also scheduled for January 12th, 2026.
According to the police report, at approximately 10:50 p.m. on October 11th, three police officers were conducting a traffic stop in the parking lot of 1 Miacomet Avenue. While the officers were conducting the field sobriety testing, they noticed an individual – later identified as Chacon – standing across the street in the driveway of 2 Miacomet Avenue in front of the garage wearing a green sweatshirt over a white shirt and tan pants. Officers said he was observing the stop for several minutes.
Shortly after noticing Chacon, a handful of small rocks were thrown at the police officers from behind while they were speaking to the operator in his driver’s seat. Police said the rocks originated from the area where Chacon was standing and that one of the rocks struck an officer in the back of the head.
The rocks thrown matched the shape and color of the gravel driveway at 2 Miacomet Avenue, and the three officers investigated the area where the rocks came from immediately after. While searching the area with their flashlight, they witnessed Chacon passing through the back yard of the neighboring house where the rocks were thrown from, 61 Surfside Road. The owner of the home told police Chacon did not have permission to be on his property, and requested that he be trespassed.
While speaking to Chacon, police asked to see his hands and observed fresh dirt and sand on his palms and fingers, which they said would be consistent with the hands of someone who just grabbed a bunch of small rocks off of the ground.
