Anne Heche remains in a coma after suffering a "severe" brain injury and is "not expected to survive," a representative for the actress told Fox News Digital Thursday evening.
The rep added that Heche’s wish had always been to be an organ donor and "she's being kept on life support to determine if any are viable."
"We want to thank everyone for their kind wishes and prayers for Anne's recovery and thank the dedicated staff and wonderful nurses that cared for Anne at the Grossman Burn Center at West Hills hospital," the statement, made on the behalf of Heche's friends and family, continued.
The rep added, "Anne had a huge heart and touched everyone she met with her generous spirit. More than her extraordinary talent, she saw spreading kindness and joy as her life’s work --especially moving the needle for acceptance of who you love. She will be remembered for her courageous honesty and dearly missed for her light."
Heche, 53, was driving a blue Mini Cooper last Friday when she first crashed into a garage of an apartment complex in Los Angeles. Shortly after, she crashed her car again into a nearby home in Mar Vista and ignited a fire.
A blood test "revealed the presence of drugs" in Heche's system, the Los Angeles Police Department told Fox News on Thursday, but "additional testing is required to rule out any substances that were administered at the hospital as part of her medical treatment."
The department said Heche is under investigation for driving under the influence in connection to the crash.
Heche's rep said Thursday that the actress had not regained consciousness since shortly after the crash.
Heche is known for movies like "Donny Brasco," "Six Days, Seven Nights" and the remake of "Psycho."
Celebrities and loved ones have sent Heche messages of support over the last week.
Alec Baldwin called her an "amazingly talented woman" and actor Peter Facinelli said he was "praying for" her and her "beautiful family." Actor James Tupper, Heche’s ex-boyfriend, reached out on Instagram with a photo of Heche and Atlas, their 13-year-old son.
"Thoughts and prayers for this lovely woman, actress and mother tonight Anne Heche," he wrote on Instagram last weekend. "We love you."
