Schenectady police have now arrested Heaven Puleski on several charges related to the discovery of the body of an infant last week.
Puleski is not directly charged with the death of the child, believed to be her four month old son, Rayen, but is accused of tampering with physical evidence, concealment of a corpse, and endangering the welfare of a child.
Police have not formally identified the remains found last week as those of Rayen Puleski, and say the investigation into the child's death will take much longer than expected.
Heaven Puleski is expected to be arraigned Wednesday morning in Schenectady.
