Deep in today’s WaPo story about the deadliest crash in Metro history is this nugget:

The first lawsuit against Metro as a result of the crash was filed yesterday, and more are expected. The parents of Davonne Flanagan, 15, of the District sued in federal court, charging “negligent operation” and “negligent maintenance” on the part of Metro and the train’s operator.

Imhotep Yakub and Dawn Flanagan are seeking $950,000 for Davonne’s fractured leg and his pain and suffering. They are represented by Lawrence Lapidus, of the D.C. office of Karp, Frosh, Lapidus, Wigodsky & Norwind. (The firm also has offices in Rockville and Alexandria.)

A search of the PACER system shows no other suits filed against WMATA this week in D.C. or Maryland’s federal courts.
