The New Jersey Office of the Attorney General is looking into a deadly 2018 crash involving Sen. Bob Menendez’s now-wife Nadine Arslanian, according to a report by the New York Times.

The Times reports that Attorney General Matt Platkin’s office will investigate how Bogota police and the Bergen County Prosecutor’s Office handled the crash investigation.

Arslanian was dating the senator at the time of the crash. She struck Richard Koop with her car, and he later died from his injuries. Arslanian told police at the time that Koop ran across the road and jumped onto the hood of her Mercedes.

A police report found that Arslanian was not at fault.

The case is now being scrutinized due to a bribery indictment involving the couple. Federal prosecutors allege that soon after the crash, Arslanian was given a new Mercedes – a vehicle that they say was given to the couple as a bribe. Prosecutors say this was in exchange for Menendez to ask the then-New Jersey attorney general to back off on a fraud investigation.

The New Jersey Office of the Attorney General told News 12 that the office could neither confirm nor deny an investigation is taking place. The Bergen County Prosecutor’s Office also could not provide any information.

Koop’s family says that they have had questions for years about if the case was fully investigated.
