A Quincy father went to police and turned in his own daughter, after spotting her in a most-wanted photo, as the bank robber suspected in a Quincy robbery and two others in the last month. Quincy police arrested 37-year-old Merredith Cunniff on Friday at her father’s house on East Squantum Street in Quincy and charged her with the unarmed robbery of the Colonial Federal Savings Bank on Beach Street. The take in the July 16th robbery was $6,000. Police also suspect that Cunniff robbed two other banks: the Sovereign Bank in Marshfield on July 19 and the Mount Washington Bank in South Boston on July 12th. When he went to Quincy police, 67-year-old Edward Cunniff, looked at surveillance photos from both bank robberies and told police that he believed the woman in all of the photos were his daughter. Cunniff had sought to get his daughter sent to a rehabilitation facility, but Judge James Sullivan did not find enough to admit her. Meridith Cunniff has been released on $1,500 cash bail. She is due back in Quincy District Court on August 29th.
