Macaulay Culkin and his siblings in their large family are reeling from the traffic accident death
of their sister Dakota, their manager tells PEOPLE.
"They're heartbroken. That I can tell you. They're just absolutely heartbroken," says Emily Gerson Saines, who manages Macaulay, Rory and Kieran Culkin.
The brothers were working on separate projects when they received the news that Dakota, 29, died after she was struck by a car Dec. 9 in West Los Angeles.
Macaulay, 28, was shooting the new NBC drama Kings
, Kieran, 26, was busy on the set of the movie Paper Man
(with Ryan Reynolds), and Rory, 19, was doing interviews to promote Lymelife
, which will be premiering at the Sundance Film Festival in January.
All of them have put their work on hold temporarily to deal with the tragedy.
The family also has brothers Christian, 21, and Shane, 32, and sister Quinn, 24.
