Iona losing her husband unexpectedly and working through her grief, along with the daughter, would put a lot of stress on anybody's shoulders. Throw in a business that still needs to be run. Hopefully, family stepped in to help.
Hmmmm. I followed one of the above links to the Southold Local news site, and wanted to see if there were any more recent articles on this, so I went to the front page of the Southold Local site and did a search for "Costello":

I'm not trying to be cryptic, but I never remember when we're allowed to post something here if there's no person of interest (so I hope I'm not violating anything--and I swear I wasn't sleuthing anyone, just looking for updates). And I really don't think the other listed "Costello" articles have anything to do with these two being missing. But I do wonder if maybe it's some of the "possible stress" that a relative (Iona's mother, I think?) had mentioned?
If it was just the mother who was missing I could see it possibly being a voluntary disappearance because of stress but getting a 14 year old girl to willingly go along with that is just not going to happen.
Holy huge tuition!
Ross school is over $36,000 per year!
Darn it! Another missing person I will have zero insight on
I really want these two be safe. I immediately like them from their photos. Their ages, interest in travel and love for animals makes us kindred spirits (excluding tax bracket, of course). She makes cheese, likes corgis, and kayaks. I really relate to this Mom and daughter.
The will signed by the thrice-married George Costello, 63, who co-owned Costello Marine Contracting, which builds docks and bulkheads, left everything to Iona and Emily.
