People v. Rebecca Grossman is a landmark 2024 California criminal case where a prominent socialite was convicted of second-degree murder for a 2020 high-speed hit-and-run that killed two young brothers, Mark (11) and Jacob (8) Iskander, in a Westlake Village crosswalk. The case drew intense national attention due to the high-profile nature of the defendant, allegations of street racing with a former MLB player, and the use of "implied malice" to elevate a fatal drunk-driving incident to a murder conviction.
