Concord, NH – Attorney General John M. Formella announces that Robert Gagnon, age 47, has been sentenced today on multiple charges in connection with the shooting of Carlos Quintong, age 46, in Brookline, and the murder of Robert Prest, age 83, in Lyndeborough, both on November 23, 2022. He was also sentenced on three class A felony counts of theft by unauthorized taking, arising from his various efforts to flee the scenes of both the shooting and the murder.

Mr. Gagnon was sentenced to 30 years to life on a second-degree murder conviction. On his attempted murder conviction for the shooting of Mr. Quintong, Mr. Gagnon was sentenced to 15 years to 40 years, with an opportunity to reduce the minimum term of this sentence by 5 years for completion of anger management counselling and not accruing any other criminal charges. The attempted murder sentence runs consecutive to his second-degree murder sentence, functionally making the cumulative, minimum term of both sentences 45 years.

On the theft by unauthorized taking charges, Mr. Gagnon was sentenced to 3.5 to 7 years on each of those convictions, all suspended 10 years from his release on the second-degree murder and attempted murder sentences.
