SKOWHEGAN, Maine — A man and woman from Pittsfield suspected in an armed robbery last month were among 17 people indicted Friday by a grand jury in Somerset County.

Robert E. Burt, 35, and Elizabeth Bernasconi Tansino, 41, each were indicted on a single charge of Class A robbery related to an incident on Aug. 23 at Deer Hill Apartments in Pittsfield.

The couple reportedly was visiting friends that afternoon when Tansino attacked another female visitor. It wasn’t clear what provoked the attack, but Tansino reportedly demanded the woman’s purse while Burt pulled out a knife to keep other visitors at bay.
