Grace Brugess, a spokeswoman for the New York City medical examiner's office, said Monday investigators will now try to extract DNA from the material to try to determine the identity of the remains, CNN reported.
Investigators had not said whose remains they have been seeking when they searched the Queens home Wednesday, but they are related to a more than 30-year-old case.
Burke, of the Luchese crime family, died in prison of cancer in 1996. He was the alleged mastermind behind the heist of $8 million at Kennedy Airport in 1978.
The mobster allegedly killed a number of men who helped pull off the heist to keep them from talking to police, the newspaper said.
