LOS ANGELES — Police say Macaulay Culkin's sister Dakota Culkin was killed after she stepped in front of a car in west Los Angeles.

Police spokesman Richard French says Dakota Culkin was struck Tuesday night after she stepped into the street. She died a day later at a Los Angeles hospital after suffering massive head injuries.

French says there is no active criminal investigation.

Police say the driver stopped and tried to help the 29-year-old. Officers determined the motorist wasn't driving drunk and followed all laws.

Macaulay Culkin's spokeswoman, Michelle Bega, said it was a "terrible tragic accident" and the family had no further comment.

The 28-year-old actor starred in the "Home Alone" films.
