The 20-year-old woman who was shot in her car in Hudson on Thursday has died, according to the Middlesex County District Attorney’s Office.

No arrests have been made, but officials say the preliminary investigation indicated the attack was targeted.

The incident happened around 2 p.m. on Howe Street, according to the DA’s office. The woman was found suffering from gunshot wounds and taken to a local hospital.

She was later taken via a medical helicopter to UMass Memorial Medical Center in Worcester where she was pronounced dead early Friday. Her name has not been released.

The shooting prompted a lockdown at Camela A. Farley Elementary School and some busing was suspended at David J. Quinn Middle School, according to an earlier release.
