before you can be convicted, the government has to prove beyond a reasonable doubt you committed the act. If there are numerous folks who could have done it, conviction seems unlikely. That is conviction, they of course can charge you with the crime and make you defend yourself, that just take probable cause to believe a crime was committed and you are the actor who committed the crime. Contact a local criminal defense attorney even if you have not been charged. Frequently a well placed phone call from counsel can cause the charges to be avoided all together.
You can be charged with an offense if the prosecutor believes there is probable cause to support htat charge. Even circumstantial evidence such as possession or constructive possession of the weapon may be sufficient to convince a prosecutor to charge out a case.
However, your attorney may challenge probable cause if charges are filed as part of a pretrial hearing. If a Judge determines the evidence too weak, the case would never even proceed to a trial.
It is important that you not post detail on the internet that could be traced back to you, because the government could use them as statements against you. The prosecutor can charge you if they determine there is probable cause as one of my colleagues noted. If you would like to get some good advice on the situation, you should contact an attorney and seek a consultation.
