On December 13th, 2013, Barnstable Street Crime Unit (SCU) members were on patrol in the Hyannis. At approximately 6:00pm, SCU members Yarmouth Officer Nicholas Ambosini and Barnstable Officer Scott Wright were in the area of Rte 132 and Bearses Way, Hyannis. They observed a gray Nissan Altima pull into the Cumberland Farms, parking lot. A young adult male and female exited the vehicle. They entered the store. After several minutes only the female exited the store and got into the vehicle. The male subject could not be located. The female began to leave the area in the Nissan Altima. A check of the vehicle’s registration plate revealed the registered owner was a female from Plymouth. The vehicle owner had an outstanding arrest warrant.

AMBOSINI and WRIGHT stopped the vehicle on Bearses Way, Hyannis. The vehicle operator was not the registered owner. The female, identified as Mercedes Pearson, age 19, of Plymouth, initially gave officers a false name. PEARSON was placed under arrest for operating without a license and false name to a police officer. During a follow up investigation at the traffic stop WRIGHT located a load .25 caliber Beretta handgun. The handgun along with a cellular telephone was in the pocket of a XL black North Face jacket. The jacket was inside the vehicle PEARSON was operating. The jacket did not belong to PEARSON. It was suspected the jacket belonged to the male subject that did not return to the vehicle at the Cumberland Farms. PEARSON was booked and bailed on the motor vehicle charges.

The vehicle was towed back to the Barnstable Police Department. A search warrant was obtained and executed on the vehicle. It was found to contain a small black backpack. The backpack contained approximately 28 grams of heroin, 3 ounces of marijuana, 3 grams of cocaine, and a digital scale. An investigation was conducted relating to the owner of the black jacket and back pack. The male subject that exited the vehicle at Cumberland Farms was identified as Timothy L Galvin, age 21, of Onset. GALVIN is the boyfriend of PEARSON. SCU members were able to obtain evidence linking GALVIN to the jacket, .25 caliber handgun, and the recovered narcotics. Evidence was also obtained indicating PEARSON was involved with GALVIN selling narcotics.
At the time of the 12/13/2013 PEARSON motor vehicle stop, GALVIN was wanted on a Plymouth Superior Court probation violation warrant. In May of 2013, GALVIN was convicted of distribution of heroin and cocaine. He was placed on probation until 2016. In November of 2013 a warrant was issued for a violation of his probation.

The Barnstable Police Department Narcotics Unit and SCU began an active fugitive search for GALVIN. Addresses in the Plymouth area and Hyannis were searched. On 01/15/2014, GALVIN was located with PEARSON at 57 Spring Street, Hyannis. GALVIN attempted to flee and was found hiding in the attic.
