On Thursday August 4th, 2014, I, Officer Christopher Collette was assigned to Somerville marked unit East Four. At approximately 19:04 hours I was dispatched to the area of Broadway, for the report of a motorist
that was nodding off behind the wheel, and driving through red lights, and was now headed east bound on Broadway. The motor vehicle was described as a red Mercury Marquis. Broadway is a public way within the City of Somerville. Officer Brioso was dispatched as well. I finally located the suspect vehicle on Broadway where it intersects with Franklin St. This is a very great distance from where this vehicle was first observed being operated in an erratic manner.
I stopped the vehicle at the intersection of Broadway and Franklin St. Via loudspeaker, I instructed the operator to pull the vehicle over and turn off his engine, which he did. As I approached the vehicle I observed that the operator was a male known to me as Mark Pantanella. I observed that Mr. Pantanella’s eyes appeared to be glassy, and his pupils “pinned”. Based on my training and experience, I knew these observations to be symptoms of Mr. Pantanella being under the influence of some substance. I asked Mr. Pantanella if he had used or taken anything, and I explained that the police had received a report for his vehicle being operated in an erratic manner. Mr. Pantanella stated that he was off drugs and was taking Suboxone. He stated that he had taken a portion of a Suboxone pill earlier in the day.
Officer Brioso and Sgt. Chaille arrived on scene. As Sgt. Chaille approached the operator, Mr. Pantanella moved his arm as if concealing something. At this point Sgt. Chaille observed what he believed to be a fresh, and bloody “tract mark” on Mr. Pantanella’s arm. Mr. Pantanella then wiped the blood from his arm, and was then removed from the vehicle. Mr. Pantanella stated that he had a capped needle that contained heroin in between the seats. I was able to locate a syringe in between the front seats. The syringe was loaded with a beige tinted liquid, that based on my training and experience, I believe to be heroin.
While speaking to Sgt. Chaille, Mr. Pantanella stated that he had injected heroin within the last thirty minutes. Mr. Pantanella was placed under arrest for operating under the influence of drugs, and possession of a class A substance. He was transported to the station to be booked.
