Corporate immigration attorney Pierre Georges Bonnefil and his wife Marysia were drinking coffee in bed and watching the news in their Manhattan apartment on the morning of Feb. 6, 2013, when she noticed something was wrong.

Bonnefil, a 55-year-old partner at Epstein Becker Green at the time, failed to answer several questions from Marysia. When she looked at him, the left side of his face was drooping and his fingers in the left hand had curled up.
