At approximately 6:30 a.m. on Nov. 23, law enforcement responded to the area of Route 13 and Townsend Hill Road in Brookline for a report of a shooting.

New Hampshire Attorney General John M. Formella announces that Robert Gagnon, age 45, has been indicted on multiple charges in connection with the shooting of Carlos Quintong, age 44, in Brookline, and the murder of Robert Prest, age 83, in Lyndeborough, both on November 23, 2022.

On February 16, 2023, the Hillsborough County Grand Jury – Southern District returned indictments charging Mr. Gagnon with one count of attempted murder for shooting Carlos Quintong with a firearm with a purpose that the crime of murder be committed. 

The Grand Jury also returned indictments against Mr. Gagnon for first-degree murder for the death of Robert Prest.  Specifically, Mr. Gagnon was indicted for purposely causing Robert Prest’s death by striking him multiple times in the head and, in an alternative count, for knowingly causing his death while attempting to commit a robbery using a deadly weapon–a hatchet.  

Finally, Mr. Gagnon was indicted on three counts of theft by unauthorized taking for knowingly obtaining or exercising control over three items: a Jeep SUV owned by Brian LaCroix of Peterborough; a firearm owned by Mr. Prest; and Mr. Prest’s BMW sedan.

Mr. Gagnon will be arraigned on these charges at a time and date to be determined in the Hillsborough County Superior Court – Southern District. 

The charges and allegations against Mr. Gagnon are merely accusations, and he is presumed innocent unless and until proven guilty.
