'She said she was going to Manhattan for Easter , ' Iona 's mother Diana Malcolmson , 80 , told Daily Mail Online . The grandmother , who lives in nearby Shelter Island , New York , said police told her that surveillance footage from the parking garage showed Mrs Costello and Emily walking away from their car on March 30 , holding suitcases and laughing .

The mother had told workers at her farm that she would be 'back on Tuesday ' but did not return on March 31st , April 7th or April 14th .

It is not believed that the Costellos owned any property in New York , according to Chief Flatley , though authorities are now looking at a wider circle of relatives that may know about their movements in the city . A spokesperson for the NYPD said that city police are working in conjunction with Southold officers , but have not yet received any sightings of the mother and daughter .
