Jake Wark, a spokesman for Conley, identified the woman as a 24-year-old Quincy resident, adding that her name was not being released because her death is not considered suspicious.

The state medical examiner’s office is scheduled to conduct an autopsy, and the cause of death has not yet been established, Wark said.
