ANCHORAGE -

The wife of an Anchorage man who disappeared while participating in the 2012 Mount Marathon race in Seward has filed a wrongful death lawsuit against the organization that hosts the yearly Independence Day event.

Peggy LeMaitre is asking for a $5 million settlement in her lawsuit against the Seward Chamber of Commerce, saying the organization showed outrageous conduct and was negligent in its duty of care toward her husband, Michael LeMaitre, and herself.

KSKA reports the lawsuit was filed last summer.

The Chamber of Commerce wants the lawsuit dismissed, saying the circumstances of Michael LeMaitre's "presumed death" have never been determined.

On Friday, no one answered a phone listed for Peggy LeMaitre's attorney, W. Sherman Ernouf. A receptionist for chamber attorney Laura Eakes says the attorney has no comment.
