BROOKLYN - A grand jury has upgraded charges to aggravated vehicular homicide against the Brooklyn man accused in a wrong-way crash that killed a police officer.

Michael Bowen, 50, was arraigned today on a 12-count grand jury indictment. He pleaded not guilty to all of the charges.

Police say Bowen was drunk when he crashed head-on into NYPD Officer Andre Menzies, of Long Island.

Investigators say Bowen's blood-alcohol level was .26, more than three times the legal limit. He was allegedly drinking brandy for 11 hours before the crash.

The crash happened last week on the Northern State Parkway. Investigators say Bowen started out driving the right way, but made a three-point turn in the middle of the road.

Menzies died instantly in the crash. He is survived by a wife and five children.

Bowen is being held on $1 million bond and faces up to 25 years behind bars. He is due back in court next month.
