Detectives with a search warrant took a sample of Heche's blood and found narcotics in her system, LAPD spokesman Officer Jeff Lee said. But toxicology tests, which can take weeks to complete, must be performed to identify the drugs more clearly and to differentiate them from any medication she may have been given for treatment at the hospital, where she remained Thursday, six days after the crash.
This latest development came after Officer Annie Hernandez told USA TODAY Monday that a warrant to do a toxicology blood test on Heche was issued Friday by LAPD.
Police said Thursday that they were still gathering evidence from the crash, and would present a case to prosecutors if it is warranted when the investigation is complete.
A representative for Heche declined to comment to The Associated Press on the investigation.
