A Coram man who allegedly committed tax fraud -- and is also under a separate indictment in Islip's dumping scandal -- had four of the initial tax fraud charges against him dismissed and replaced with higher charges in court Friday.

Christopher Grabe, 38, of Islandia Recycling, was arrested in March for allegedly evading nearly $30,000 in state taxes and charged with two class D felonies of criminal tax fraud in the third degree; one class E felony of criminal tax fraud in the fourth degree; and one class E felony of offering a false instrument in the first degree for filing, according to the criminal complaint.

In June, he pleaded not guilty to a seven-count felony indictment and was arraigned on three counts of third-degree criminal tax fraud, one count of first-degree offering a false instrument for filing and three counts of third-degree criminal tax fraud, according to the indictment.

During the brief court proceeding in front of Acting County Court Judge Gaetan B. Lozito Friday morning, a prosecutor moved to dismiss four counts in light of the indictment. Lozito granted the application.

Grabe and his attorney, Alia F. Richards, were not required to make an appearance. Richards has said Grabe will "defend it to the fullest."

Along with five other men and four companies, Grabe has also been indicted on charges related to a dumping scheme in and around Islip Town. He has pleaded not guilty to those charges and is due back in court on that case Sept. 29.
