The sons of a woman who died of smoke inhalation in an accident on a Yellow Line Metro train filed a $50 million lawsuit on Jan. 30 against the Washington Metropolitan Area Transit Authority.

Carol I. Glover, 61, died Jan. 12 when a train bearing her and hundreds of other passengers encountered heavy smoke near the Lโ€™Enfant Plaza station. Glover, who suffered from asthma, was overcome when smoke filled her train car and could not be revived despite the efforts of fellow passengers. 80 others were hospitalized.

Marcus W. Glover and Anthony R. Glover II were joined at press conference announcing the lawsuit by their attorney, Patrick Regan of Regan, Zambri & Long PLLC in Northwest D.C.

โ€œThis is a very important day, we want to make sure this will never happen again,โ€ Marcus Glover said. โ€œWe want to seek justice for our family, but for everyone in this city โ€“ we are not bitter, we seek justice.โ€

โ€œMy family has been devastated by this tragedy,โ€ Anthony Glover said.  โ€œWe are completely and utterly devastated by the loss of my mother.โ€

Anthony Glover said he remained in close contact with his mother during his service in the Marine Corps and through three deployments in Iraq.

Hundreds attended a Jan. 19 memorial service for Glover at Capitol Hill Baptist Church in Northeast D.C. She was a Washington, D.C. native and resided in Alexandria, Va. at the time of her death.

The National Transportation Safety Board is investigating the incident; completion of a final report is expected to take several months. According to The Washington Post, a preliminary report found that an โ€œelectrical arcing incidentโ€ caused smoke to fill the tunnel.

The 10-page lawsuit filed in U.S. District Court in Washington D.C. cites negligence on the part of Metro responders in following safety measures and evacuating the stricken train in a timely manner.

โ€œAs a direct and proximate result of Defendant WMATAโ€™s negligence, Ms. Glover was trapped, helpless, in Train 302 for nearly forty-five minutes as it filled with smoke,โ€ the lawsuit states, โ€œduring this time she fought, ever more agonizingly, to breathe as the smoke gradually sapped the life from her body.โ€

โ€œShe was a fabulous type of woman, Carol was; as a mother, grandmother, daughter, sister, and citizen,โ€ Regan told the AFRO following the press conference. โ€œShe was fantastic.โ€

โ€œI had asked her sons to do the press conference on what was lost in this senseless tragedy on Jan. 12,โ€ he added. โ€œCarol had three grandchildren, one on the way and that was the purpose. The family is not greedy or vindictive but they want to make sure that this doesnโ€™t happen to anyone else on this subway system.โ€

โ€œMetro should have evacuated the passengers off that subway train long before anyone was injured or killed,โ€ Regan said.
