Macaulay Culkin's sister Dakota had alcohol in her system the night she was struck by a car and killed.

Los Angeles coroner Fred Corral has revealed the 29 year old had been drinking and was "more than likely impaired due to alcohol," when the accident took place in the city on December 9th. The medical expert has not revealed how much alcohol was in her system - but confirmed Dakota was undergoing alcohol counseling prior to her death, information provided by the Culkin family.

Dakota's five siblings - who include Home Alone star Macaulay - were left "absolutely heartbroken" by the death.
