A 25-year-old man has pleaded not guilty to setting a fire at a western Massachusetts home that killed two of his neighbors. It was one of nine fires set within hours of one another in the community of Northampton.

Anthony P. Baye was ordered held without bail Tuesday at his arraignment on two counts of murder, arson and armed burglary in Northampton District Court. He has not been charged with the other fires.

Prosecutors said in court that Baye was caught on surveillance video in the area the night of the fires. They said that proves his alibi — that he was visiting his girlfriend — was a lie.

The Dec. 27 blaze killed 81-year-old Paul Yeskie Sr. and his 39-year-old son, Paul Yeskie Jr.

Baye lives in the Yeskies' neighborhood. A woman who answered the phone at the Baye home Tuesday declined to comment.
