The announcement came
hours after 52-year-old Gayle Johnson was struck just before 7 p.m.
and dragged half-a-mile. The vehicle left the scene and the incident was
initially called a hit-and-run by authorities.
The unidentified driver has not been charged at this time, according to Jake Wark, a spokesman for Suffolk County District Attorney Dan Conley.
“He did not show signs of impairment; he was subjected to drug and alcohol testing pursuant to MBTA policy, the results of which must be subpoenaed by investigators,” Wark said in a statement Wednesday.
It’s not clear yet if the driver was aware the woman was hit or dragged.
Massachusetts State Police have
taken over the investigation.
