RIVERHEAD - The Selden man who pleaded guilty in a crash that killed two teens is facing serious new charges and has had a previously agreed upon plea deal pulled off the table.

David Heise pleaded guilty May 10 to criminally negligent homicide for a crash that killed two Connetquot students.

As News 12 Long Island has reported, last week Heise was behind bars less than a day when he was charged with smuggling drugs into the jail in a balloon he allegedly stuck into his body.

In court today, Judge James F.X. Doyle blasted Heise saying, "This behavior is completely unacceptable" and pulled his plea deal off the table. With the deal, Heise could have gotten off with a sentence of one and a third to four years in the deadly accident. Now prosecutors will push for the maximum, which could keep him behind bars for more than a decade.

Heise will be back in court tomorrow to face charges of bringing drugs into the jail. He'll be sentenced on the original fatal accident charges in August.
