On Friday, actress Anne Heche reportedly crashed her car into a Los Angeles home. The accident left her in a coma for several days before she succumbed to her injuries and died. After eye-witnesses claimed to have seen her speeding down the road, investigators issued a drug test that found Heche had narcotics in her system. TMZ reports that law enforcement listed cocaine and fentanyl as the drugs found in her system. Heche was specifically under the influence of cocaine at the time of the crash. It is "unknown at this time" if those are the only narcotics that caused the blood test to turn up positive, says an LAPD spokesperson.

Eyewitnesses and doorbell cameras saw her driving her blue Mini Cooper at high speeds before crashing into the home of Lynne Mishele, who suffered injuries from debris and smoke inhalation. As a result, it was reported Thursday that Heche was under investigation for felony DUI charges. For a car crash to be a felony, it has to cause injury to others.
