A 54-year-old Hudson, Mass man will be arraigned Wednesday, Jan. 20 in Cambridge District Court charged in an alleged road rage incident that turned deadly on a quiet Belmont side street on Tuesday afternoon.

According to a joint announcement by the Belmont Police Department and the Middlesex District Attorney, Dean Kapsalis is facing at least one count of assault and battery with a dangerous weapon, his pickup truck, after he struck an unidentified 35-year-old Boston man who had just “engaged in a verbal altercation” with Kapsalis on Upland Road at approximately 4:22 p.m.

Upland Road runs from Slade Street to Beech Street at the entry of the Beech Street Center.

The investigation found that the two men got out of their vehicles and began verbally sparing after some kind of traffic dispute. Police said during the clash of words, Kapsalis reentered his Dodge Dakota and allegedly struck the victim as he was heading to his Honda Civic. Police reported Kapsalis then fled the scene.

Belmont Police responded to a 911 call and located the victim suffering from life threatening injuries in the roadway near the driver’s side of his vehicle. First responders provided emergency assistance to the man who was transported to an area hospital where he later died from his injuries, according to the announcement.

The identity of the victim is being withheld pending next of kin notification.

Approximately 30 minutes after the incident, Kapsalis arrived at the Belmont Police Department. Police and the DA said this is an active and ongoing investigation and additional charges are possible.
