WESTPORT - A woman living in New York is facing numerous charges after she tampered with relatives' drinking water while staying at a Westport home, police said.

Megan Greenlee, 50, of Pleasantville, is charged with two counts of assault of an elderly person, two counts of second-degree assault, second-degree failure to appear and failure to comply with fingerprinting requirements, police said.

An investigation began after residents reported being ill, with the same symptoms, resulting in two calls in a day on July 4, police said. Three residents needed to be taken to the hospital, one of them twice, police said.

"Through police led interviews with these patients, they expressed a concern that a relative residing in the home, identified as Megan Greenlee, might be responsible," police said. "Investigation of these claims led detectives to a communal water container within the home that was found to contain an unknown sediment."

Greenlee was believed to have tampered with the water after labs showed a prescription medication in provided samples, police said. Investigators found "a link between the medication and Greenlee," police said. They did not say what the medication was.

Police said Greenlee was taken into custody by officers in Westchester County after she failed to respond to multiple contact attempts. Police said she was transported back to Westport on Feb. 25, when she was formally charged.

Greenlee appeared to remain in custody as of Wednesday, according to records, and was scheduled to appear at state Superior Court in Stamford May 5.
