THE BRONX

* A 75-year-old New Jersey man was found dead yesterday inside his Toyota, which had plunged into a Throgs Neck creek, police said.

The cops received a call at 9:40 a.m., telling them that a motorist, later identified as Chen Chang of Norwood, had driven into Hammond Creek, not far from the Throgs Neck Bridge.

The partially submerged vehicle was missing a tire that was later found quite a distance away, a police source said.

Investigators were not immediately able to say whether this was an accident or a suicide.

Chang had been missing for two days and was “taking medication” for an undisclosed ailment that may have “left him confused or delirious,” a source said.
