Socialite magazine publisher, 57, is charged with DUI hit-and-run after she 'kills two young brothers in front of their parents - carrying one on her hood for 100ft' - as cops probe whether she was street racing her Mercedes

A former magazine publisher has been arrested for allegedly killing two young brothers in a hit-and-run crash while under the influence of alcohol in California. 

Rebecca Grossman, 57,  who is a co-founder of the Grossman Burn Foundation, was arrested on suspicion of manslaughter and DUI after smashing her speeding Mercedes into brothers, Mark and Jacob Iskander, in Westlake Village, police said. 

Mark, 11, died at the scene while his nine-year-old brother, Jacob, died in hospital a few hours later.

The young boys were 'walking with their family' at the time of the tragedy, according to Capt Salvador Becerra of the Los Angeles County Sheriff's Department.

'It is a very tragic situation. The mother and father were able to pull the other two children back in time, and the vehicle struck the two other children,' Becerra said.

Investigators said one boy was carried 100ft on the hood of the car before she braked, at which point he fell off the car and she ran him over again while fleeing the scene. 

Investigators said street racing may have been involved and claim Grossman is not cooperating with detectives.  

Grossman is part of the prominent Grossman family and along with her husband Peter, founded the Grossman Burn Foundation.

She is also the former publisher of Westlake Magazine.

Police said the crash took place at 7.10pm at the intersection of Triunfo Canyon Road and Saddle Mountain Drive.

Six family members were crossing the three-way intersection on a marked crosswalk on the road with no stoplight.

The mother heard the speeding Mercedes and both parents reached out to protect their children and grabbed two of them but the two brothers were too far away and were hit by the car, police said.

One of the boys was carried for more than 100ft down the road on the hood of her car before she hit the brakes, according to KABC. 

The boy then rolled on to the street and she ran him over while leaving the scene before pulling over a mile and a half away, detectives said. 

Grossman was booked on suspicion of vehicular manslaughter and DUI and her bail was set at $2million
