New York Inspector General Lucy Lang's office on Monday was urged by Republican Sen. Jim Tedisco to provide an update on the investigation of the Schoharie limousine crash that killed 20 people in 2018. 

Tedisco urged the office, which investigates executive branch agencies, to provide more details into the probe so lawmakers and a limousine safety commission could potentially craft further legislation and regulation if needed. 

"We're talking about a new administration, new transparency," Tedisco said. "I'd like the inspector general to tell me did you complete that investigation? Did you not complete that investigation? Who was responsible for this? Was DOT responsible for this in some sense? Do we need more regulations?"

The investigation into the state's handling, oversight and potential responsibility of the crash has been underway for at least a year. Lang became inspector general in late 2021.  

"The matter is under review," said Lee Park, a spokesman for Lang.

Tedisco had requested the investigation last year after the National Transportation Safety Board reported the state Department of Transportation and the Department of Motor Vehicles share blame alongside the owners of Prestige Limousine for not removing the limo from the road. 

"We have to get to the bottom of this and figure out whose culpable and who caused this disaster," Tedisco said. 

State lawmakers have previously approved a package of measures meant to tighten limousine safety regulations in the state in the wake of the crash.
