Staff members of a Northeast Miami-Dade nursing home say they had no hand in the alleged disappearance of $2 million from a former resident. The resident’s son is suing in Miami-Dade Circuit Court, claiming that facility leaders did not screen staff members well enough.

Pianist Avigdor Ziskin, now 79, lost the majority of his $3 million-plus net worth while living at Regents Park at Aventura from 2009 to 2015, according to his son, Zachary. The younger Ziskin filed a 19-page lawsuit against Regents Park on June 21.

The administrator at Regents Park declined comment Tuesday. He referred McKnight’s to comments from the facility’s lawyer in a Miami Herald article. “We disagree with the allegations and will take all appropriate legal action to defend our client,” said the lawyer, Allison S. Bernstein.

Miami-Dade police could not find a case involving a financial crime against the elder Ziskin, according to the Herald story.

The younger Ziskin claims that staff members would use his father’s financial accounts to write checks to themselves. They would allegedly force Ziskin to sign, or outright forge his signature themselves, the lawsuit claims.
