Random Attacker Convicted and Sentenced
Clauvens Janvier, 29, of Waltham, has been convicted and sentenced in Middlesex Superior Court in connection with a string of unprovoked violent assaults on strangers during the pandemic. He is shown above in a 2015 photo, when he was a student athlete at Waltham High School.
This week, Janvier “pleaded guilty to twelve separate assaults that occurred in public areas of Waltham over a 30-day period in November of 2020,” according to the Office of Middlesex DA Marian Ryan. She is shown in March 2021, when charges were first announced during a press conference in Waltham.
“During several of the attacks the defendant used a weapon including a machete and in one assault the defendant also used a firearm,” said the DA this week.
Most of the assaults took place in Garden Crest and on the South Side and involved male victims unknown to Janvier, including some who lost consciousness or required hospitalizations. One victim was a USPS letter carrier.
Janiver was arrested in December 2020 in connection with a single assault on an 18-year-old male involving the non-blade side of a machete in a parking garage near Brandeis.
An intensive investigation managed “to place the defendant in the area of the assaults and determined that he was responsible for multiple attacks that had recently occurred across the city of Waltham.”
In addition to the assaults, Janvier was also convicted on firearm offenses in connection with a shots-fired incident involving a motor vehicle leaving a Willow Street gas station in late November 2020. The gunfire followed a verbal altercation with a man in the station parking lot, the DA said.
A Middlesex Superior Court Jury convicted Janvier on the firearms charges in November 2025 and on the assault charges this week.
“The defendant was sentenced to 14 years and one day on the three counts of assault and battery with a dangerous weapon causing serious bodily injury,” the DA said, “eight to ten years on the five counts of assault and battery with a dangerous weapon; and, three years of probation (consecutive to the prison time) on the assault and battery and carrying a dangerous weapon charges.”
The DA said Janvier was also “sentenced to a concurrent sentence of seven to nine years for possession of a firearm in the commission of a felony; four to five years for two counts of possession of a firearm; two and a half years House of Correction for the two counts of possession of a loaded firearm; three months House of Correction for one count of discharging a firearm; and, three years of probation from and after for one count of assault by means of a dangerous weapon.”
