CONCORD — A Raymond man convicted two years ago of multiple arsons and killing four dogs in a 2015 crime spree had an appeal of his decades-long prison sentence denied by the state Supreme Court.

The state’s highest court upheld Gregory Bruno’s 22˝- to 60-year prison sentence following his June 2017 conviction on more than 28 charges, including two counts of animal cruelty, four counts of arson and six counts of attempted arson, Rockingham County Attorney Patricia Conway announced Tuesday.

Bruno set off a string of fires throughout Epping, Raymond and Stratham between January and May 2015 with two resulting in the deaths of four dogs. During his trial in Rockingham Superior Court, prosecutors argued Bruno’s “reign of terror” stemmed from a breakup with his then-girlfriend.

In addition, Bruno sent threatening, anonymous messages to the woman and many others. One of the fires he was convicted for was set to his ex-girlfriend’s residence in Raymond and another set to a car parked at the Planet Fitness in Stratham that killed one dog. Even after his arrest, Bruno continued his violent behavior from the Rockingham County jail, where he solicited inmates to set fires when they were released from prison, prosecutors said during the course of the trial.

The Supreme Court rejected Bruno's assertion on appeal that the trial court erred in joining the charges against him, affirming the trial court's ruling the charges were logically related even if not committed as part of one criminal episode, Conway said.

"I am pleased that our state's highest court has upheld this conviction," Conway said. "The Supreme Court agreed with the trial court in determining that these charges are all directly related to one another, and that justice was served as it relates to Mr. Bruno's heinous crimes."

Deputy County Attorney Jennifer Haggar served as the prosecutor on the case, which was resolved following a 15-day trial in June 2017.
