MANCHESTER — The 32-year-old man killed last week when the car driven by his fiance crashed at high speed into another car on Granite Street was a Nashua native who just celebrated 13 months of sobriety — and, according to his family, used his experience “to help countless others who were struggling with addiction.”

Michael B. Shattuck was the passenger in the 2021 Acura driven by his fiance, Ailadi Archilla, who is also identified as Ailadi Abreu, 35, of Manchester, when Archilla allegedly accelerated to speeds estimated at 80 mph on the I-293 north off-ramp and lost control while attempting to turn left, resulting in her vehicle colliding head-on with a BMW driven by a 64-year-old woman, according to police.

Officers, firefighters and medical personnel arrived at the scene to find bystanders performing CPR on Shattuck, police said. Despite their efforts and those of paramedics, Shattuck died at the scene.

Archilla was heavily entrapped in the wreckage of her vehicle, and firefighters went to work to extricate her while paramedics provided medical care. Once freed from the vehicle, Archilla was transported to a local hospital with serious injuries, from which she continues to recover.

Following an investigation into the incident, police charged Archilla with one count each of manslaughter and negligent homicide and two counts of reckless conduct.

She was booked in absentia, then arraigned via video from her hospital bed on Friday.

The driver of the BMW was transported to the hospital for evaluation, and was treated for minor injuries, police said.
