Broadway actress Megan Hilty is in mourning after several family members died in a plane crash.

King 5 reported that Megan's sister Lauren, who was pregnant with her second child, was aboard the plane — as was Lauren's husband, Ross Mickel, and their child, Remy

The crash site is about 30 miles from Seattle.

"We are deeply saddened and beyond devastated at the loss of our beloved Ross Mickel, Lauren Hilty, Remy and their unborn baby boy, Luca. Our collective grief is unimaginable," Ross's family said in a statement.

The cause of the plane crash isn't known. TMZ reported that one body had been recovered before the search was suspended on Monday.

Megan, who starred in "Smash," "Annie Live," and several Broadway shows, including "Wicked," has not publicly commented on the tragedy.
