State police didn't say what Mark T. Donahue is suspected of doing in the alleged murder attempt, which took place in Marlborough, east of Worcester. Troopers began chasing Donahue in his 2022 Toyota Highlander SUV in Weston, on State Route 20, then followed him as he drove onto I-95, then I-93, police said, noting that he was suspected of having a knife.

The chase ended shortly after 10:15 p.m., when the SUV drove over stop stick tire-deflation devices that troopers had put on I-93, allowing cruisers to box the vehicle in south of the highway's Granite Avenue exit, police said. A number of police vehicles and an ambulance were seen on I-93 north, causing a traffic backup.

Donahue was found inside the SUV with "serious, suspected self-inflicted lacerations," police said in a statement, and he was taken out for first aid.

Donahue was placed in the custody of Marlboro police, according to state police. It wasn't immediately clear if he had an attorney who could speak to his arrest.

Marlboro police would only characterize the incident that led to the pursuit as a "disturbance," and said the nature of what happened prevented them from sharing more details. The investigation was ongoing as of Friday.
