Macaulay Culkin's sister, Dakota, was struck and killed by a car in Los Angeles this week, police confirm.
The 29-year-old stepped in front of a car in West L.A. just before 11 p.m. on Tuesday and was rushed to UCLA hospital with massive head trauma, according to LAPD spokesman Richard French. She died the following day.
"The driver stopped, rendered aid, and identified himself as required by law," said French. "Detectives determined that the driver was not under the influence of drugs or alcohol and that no crime was committed."
Macaulay Culkin, 28, has five other siblings: Shane, 32, Kieran, 26, Quinn, 24, Christian, 21, and Rory, 19.
"This is a terrible tragic accident," said the actor's rep, Michelle Bega. "We ask that the media respect the family's privacy during this difficult time."
The accident was first reported by TMZ.com.
