CBS in New York is reporting that along with the prescription drugs that were found in the apartment, police also recovered a rolled up $20 bill with narcotic residue on it.
Sources add they also found several drug packets containing an unknown substance. CBS 2 has learned these items were all listed on the official police report from the scene.
Those substances were officially vouchered, meaning they have been taken by police, listed in their initial reports, and sent to a lab for testing.
Commissioner Ray Kelly confirmed during a news conference Wednesday that the bill was found on the floor near Ledger's bed and being taken for testing. But he added there was no visible residue on the bill.
To be clear, it's still unknown whether these items belonged to Ledger, whether he even actually ingested them, or whether the substances are illegal. To see the video of this story, you can click here.
