A 41-year-old Milford woman has been identified as the person fatally struck by an Amtrak train Tuesday at the Southport Railroad Station.

Jennifer Battista was identified Thursday afternoon as the victim in the continuing investigation into the incident by Metropolitan Transportation Authority police, according to Aaron Donovan, an MTA spokesman.

Although circumstances of the woman’s death remain officially undetermined by the investigation at this time, Donovan said, the reason that she was on the tracks does not appear to be either accidental or criminal.

Battista was on the eastbound tracks at the station without authorization, investigators had said previously.

The office of the state’s chief medical examiner is also involved in the investigation.

The woman was hit about 2 p.m. Tuesday by an Amtrak train while she was on the tracks just before the depot’s eastbound passenger platform.

About 200 passengers were on the northbound train, which began its run about 6 a.m. in Virginia and was headed to Boston, and they were transferred to another Amtrak train that arrived later in the afternoon.

Rail service delays were reported for several hours in the aftermath of the incident.

Battista’s death is the latest in a series of fatalities in a series of deaths on railroad tracks through the region over the last several months.

On Sept. 9, the Rev. Colin J. McKenna, a Catholic priest from Wilton, was struck and killed by a Metro-North train east of the Saugatuck Railroad Station in Westport. McKenna’s death was investigated as a possible suicide.

A 28-year-old Stamford woman, who apparently jumped or fell Aug. 7 onto the tracks in front of an approaching train at the Cos Cob station, was killed as some witnesses said she appeared to be trying to retrieve her purse.

Her death, however, was later ruled a suicide by the state medical examiner.
