The autopsy performed yesterday failed to give a conclusive answer as to how Amy Winehouse has died.
The police are now considering the reason of death as unknown, but not suspicious.
Although nothing alarming has been found in her body, the results of the toxicology tests are expected to come in 2-4 weeks.
Previous reports claimed the Rehab singer had died due to an overdose of drugs and alcohol.
However, police investigators have said that there were no signs of drugs in her London home. Amy died alone in her bed and was discovered by one of her security gurads.
Yesterday the singer’s parents, Mitch and Janis Winehouse, had to formally identify their daughter at the morgue.
The funeral will be held today in London, according to Jewish tradition.
