Dunn and Lyons: A Tale of Two-High Profile OUI Cases [OPINION] Massachusetts State Police busted the Mattapoisett's chief of police on suspicion of operating while under the influence of alcohol over the weekend. Chief Mary Lyons, 61, was hauled in Saturday night after allegedly being observed driving erratically on Route 28 in Bourne. For Elizabeth Warren supporters, that's "burn." After administering a field sobriety test at the scene, police arrested Lyons and booked her at the Bourne State Police barracks. She was released on personal recognizance and is pending arraignment in Falmouth District Court. Lyons' "by the book" arrest contrasts to the crazy, mixed-up mess involving a high-profile New Bedford resident back in May. Investigating officers did not administer a field sobriety test to Ward 3 City Councilor Hugh Dunn when he smashed into two parked cars and a curb in the wee hours of the morning.
