Hopkinton police arrested a Whitinsville man suspected of dealing cocaine after an officer noticed an erratic driving pattern this past Friday morning.

Calvin Hodge, 40, was charged with drug possession to distribute a Class B substance, operating under the influence of intoxicating liquor and negligent operation of a motor vehicle. His bail was set at $2,500.

Shortly after 1:30 a.m., Officer Brennan Grimley was driving eastbound down West Main Street when he observed a gray Jeep traveling on West Main Street toward Upton. The vehicle was driving about 20 mph in a posted 45 mph zone, “which attracted his attention, so he turned around to observe the vehicle driving,” according to a Hopkinton Police Department statement. The Jeep was spotted swerving and drifting half into the opposite lane, prompting Grimley to conduct a traffic stop.

Grimley and fellow Officer Matthew Santoro inspected the vehicle. They discovered a “large wad of cash” totaling $808 in the Jeep’s front cup holder, along with 20 individually wrapped baggies of what they believed to be crack cocaine in the center console, the HPD stated. The substance weighed approximately 12 grams. Immediately after the discovery of what was suspected to be drugs, the officers stopped their search and a search warrant was requested.

“Based on the presence of a large amount of cash located within close proximity to individually packaged narcotics, [Officer] Grimley believed the possession of the narcotics was for distribution,” according to the HPD statement.

The Jeep was seized, “as there may be more evidence of further crimes located within the vehicle,” the HPD stated.

Police Chief Joseph Bennett did not immediately return a message seeking more information.

UPDATE, June 15: The HPD announced that three days after the arrest, after a search warrant was obtained, a plastic bag believed to contain 45 grams of cocaine was found inside a backpack in the rear seat area of the Jeep. That brought the total of suspected narcotics to 57 grams.

The HPD noted that according to state law, any amount more than 18 grams is considered trafficking.
