The Allegheny County Medical Examiner's Office said 54-year-old Anthony Cugini was found Wednesday morning at about 8:30 a.m. at the Wingfield Pines Conservation Area.
A determination of the cause of death is still pending, but police said it may have been an accident.
In November a Pittsburgh grand jury indicted Cugini on obstruction of justice charges.
Cugini became NETL's director in 2010, and resigned on Oct. 11. No reason was given for the resignation.
