The last wrongful death lawsuit remaining from the Sept. 11 terrorist attacks has been resolved with a settlement. Attorney Donald Migliori said Monday that the family of Mark Bavis decided to settle after making public as much information as they could about what they viewed as security lapses on Sept. 11, 2001, at Boston’s Logan Airport.

Mr. Bavis was aboard United Airlines Flight 175 when it took off from the airport and was crashed by hijackers into the World Trade Center’s south tower. Mr. Bavis was a West Newton, Mass., scout for the Los Angeles Kings hockey team.

The suit was brought by his mother, Mary Bavis. Settlement terms were not disclosed. A lawyer for the airline and a security company could not be immediately reached Monday for comment.
