WOODBURY - A landmark drunken-driving conviction was challenged today in Nassau County.

An attorney for Martin Heidgen, who was the first drunken driver ever convicted of murder in the county, argued his client should have been charged with manslaughter, not murder, in the deaths of 7-year-old Katie Flynn and limo driver Stanley Rabinowitz after colliding with their limo.

The attorney said the Valley Stream man had been drinking and did slow down significantly when he noticed the limo in front of him while driving the wrong way on the Meadowbrook Parkway.

It could take the court months to come to a decision on the appeal. Heidgen is serving a sentence of 18 years to life in prison.
