BOSTON -- Three people were arrested after a cocaine transaction at an Everett home, according to police.

The arrests followed a month-long drug investigation of cocaine distribution in Everett and Malden by detectives from the two towns and state police troopers.

Police arrested George Graef, 33, and John Mazzeo, 27, both of Everett, and Jennifer Verderber, 21, of Medford.

Verderber and Mazzeo are accused of driving a white Ford Bronco to Graef’s home on Stuart Street and receiving a package believed to be cocaine from him, according to police.

The pair then reportedly drove to Clark Street, where Mazzeo exited the vehicle and gave a small plastic bag to the driver. Officers arrested Mazzeo and Verderber and returned to the Graef’s home, where they found 60 grams of cocaine, about $2,900 in cash, scales and other drug paraphernalia, police said. Graef was arrested at the home.

All three are scheduled to be arraigned in Malden District Court on Monday.
