LOWER ALSACE TWP., Pa. -

Police say a mentally disabled woman was taken advantage of and robbed of thousands of dollars.

They say the crime of opportunity started in the 700 block of North 25th Street in Lower Alsace Township. Three women, all diagnosed with developmental disabilities, lived there.

But one of the women in particular became the target of an elaborate scheme when it was discovered she had a large trust fund of $500,000.

Police say Jeannette Snider, 75, who previously worked for ARC Alliance, began taking over the woman's finances illegally and writing checks to herself and two of her friends.

"Jeannette Snider, we feel that she saw an opportunity because she saw how much money this victim had and she realized she could get access to it and took advantage of her not knowing what she was doing," said Central Berks Regional Police Detective Deron Manndel.

Detectives say between 2008 and 2012, Snider cost the victim more than $47,000.

Snider allegedly wrote more than $9,000 in checks to Margaret Bradley who worked for Abilities in Motion.

She also allegedly paid more than $3,800 to Sandra Kreider, who previously handled the victim's finances through ARC Alliance.

Police say all of the payments were made with the victim's money, without her knowledge.

"I guess it is just something that money does to people," said Manndel.

Neighbors say they are shocked to hear the news.

"It is horrible to hear that because obviously handicapped people, they need all the help they can get. So to be stealing from them, that is horrible," said Michael Kirtner of Lower Alsace Township.

All three women are facing numerous felony charges including forgery, theft by deception and receiving stolen property.

Their preliminary hearings are scheduled for May 21.
