According to New York Penal Law 、215.40(2), a person is guilty of Tampering with Physical Evidence when “[b]elieving that certain evidence is about to be produced or used in an official proceeding or a prospective official proceeding, and intending to prevent such production or use, he suppresses it by an act of concealment, alteration or destruction, or by employing force, intimidation or deception against any person.” New York criminal defense attorneys, such as the former Manhattan prosecutors at Saland Law PC, can tell you that this crime is often charged as Attempted Tampering with Physical Evidence in an all too common scenario played out on the streets of New York City when a person discards contraband (marijuana, cocaine, heroin or even a weapon such as a knife or gun) after being confronted by the police. The question that exists in these cases is must the complaint charging the individual establish the officer’s knowledge as to what the evidence is as well as the basis of that knowledge?
In a decision rendered on July 8, 2009 in Manhattan Criminal, People v. Anthony Estrada, 2009NY005091, a man was alleged to have thrown marijuana leaves up into the air as the police attempted to arrest him. As a result, the the officer was unable to recover the alleged contraband. In dismissing the complaint, the court found, among other things, that the officer did not establish that the substance in question was marijuana.
