Carocciolo is Gianni Agnelli’s widow who died in 2019.

She was mentioned by Turin’s tribunal in a decree last week that ordered the preventive seizure of 74 million euros of assets from her three grandchildren and two other people under investigation.

Investigators believe they were part of mechanisms to artificially reduce the value of Caracciolo’s inheritance in order to minimise taxes.

Last week, the Turin court ordered the seizure as part of its investigation into Gianni Agnelli’s inheritance.

Some of the assets were seized from Stellantis chairman John Elkann, who is also the CEO of the Agnelli family holding company Exor.

Others were taken from the Ferrari chairman, his siblings Lapo and Ginevra, Turin accountant Gianluca Ferrero and Swiss notary Urs Robert Von Gruenigen.

Von Grunigen was the executor of Marella’s will.

Fraud against the state in relation to inheritance tax is reportedly among the alleged crimes being probed.
