Investigators at Volkswagen are not only looking for the culprits who installed illegal emissions cheating software into their cars, but they’re also looking for managers who didn’t immediately report the devices as well, the New York Times reported.
Up to 10 managers and engineers could be suspended by the automaker for the scandal so far, including top-level executives.
According to the New York Times, investigators have been keen to learn who knew what within the automaker, and how quickly those findings were reported.
The investigation by U.S. firm Jones Day could take months, according to the report. A person who was briefed on the inquiry told the newspaper what investigators were looking for.
Volkswagen of America CEO Michael Horn told congressional investigators he was made aware of a potential problem in the spring of 2014, but wasn’t aware of illegal software until Sept. 2015.
