PORTLAND — A candlelight vigil will be held for a missing Scarborough woman Friday.

Megan Waterman, 22, was last seen early this month on New York’s Long Island. Her family is alarmed because she normally would be in touch with her young daughter a few times each day when she was away.

The vigil will begin at 7 p.m. in the bandstand area of Congress Square on Congress Street, next to the Eastland Park Hotel.

On Saturday morning, volunteers will be gathering at the Scarborough Walmart parking lot at 100 Gallery Blvd. Volunteers will be asked to distribute missing posters in the area. Balloons with small versions of the poster will be launched. The event begins at 8:30 a.m.

More information about the events is available at www.meganwaterman.com.

Police believe Waterman worked as an escort and that she may have been in Long Island for that reason. She has not been in touch with friends or family since the weekend of June 5, when she was staying at the Holiday Inn Express in Hauppauge, N.Y.

Scarborough Detective Don Blatchford said today that police continue to investigate but that there have been no sightings of Waterman.

Anyone with information that could help locate Waterman is asked to call Scarborough police at 883-6361 or their anonymous tip line at 730-4200, ext. 3093.
