NEW YORK (WPIX) --  Suffolk County police have arrested a mother and son who are accused of running "a family identity theft business" in which some of the victims were reportedly deceased.

Tonia Cheeseman, 63, of Ridge and her son Michael Cheeseman, 41, were arrested Monday on identity theft charges, according to police.

Prosecutors say Tonia Cheeseman worked at a doctor's office and acquired the identities through patient files. She was charged with three counts of second-degree identity theft and one count of first-degree scheme to defraud.

Her son, Michael, was charged with three counts of second-degree identity theft, first-degree scheme to defraud, third-degree assault and fourth-degree criminal possession of a weapon. The assault charge was reportedly related to a domestic incident.

The identities the suspects allegedly stole included residents of Suffolk County, some of them deceased and residents in Florida where the pair had previously lived before moving to Long Island.  Police say they swiped the personal information in order to make various purchases.

Authorities are still investigating the crime and are attempting to locate additional victims.

An attorney for Tonia Cheeseman said told reporters these are only allegations and there was insufficient evidence.

The suspects are expected to be arraigned Tuesday in Central Islip.
