The Justice Department may drop its criminal prosecution of Boeing for allegedly misleading U.S. regulators about the 737 Max jetliner before two of the planes crashed and killed 346 people.

Boeing has reached a tentative nonprosecution agreement with the U.S. Department of Justice in a fraud case stemming from two fatal 737 MAX plane crashes that killed 346 people, people familiar with the matter said.

Lawyers for the families who lost loved ones in the crashes of two 737 Max jets said the DOJ intends to drop all criminal charges against Boeing.
