Authorities have said the 54-year-old Maddox was piloting the twin-engine Beechcraft Baron, which crashed into a tree and sign after an aborted landing. However, his wife says he wasn't at the controls at the time of the crash.
The plane was carrying blood and urine specimens for Quest Diagnostics, a testing firm with an office near the Bergen County airport.
The cause of the crash remains under investigation.
