Can i press charges against a group of people who jumped me.

I don't practice in MO, but surely you can make a police report and fill out a criminal complaint naming the defendants. If not, contact the prosecutor's office bring your narrative, names of the wrongdoers, medical records, photos, etc. and ask that the case be reviewed for a criminal charge.

The story you recount is quite amazing as set forth. If you are not successful on the local level I would the Missouri Attorney General's Office. You might also seek the assistance of an attorney to help advocate for you. Good luck.

If the police will not help you I strongly suggest you contact a local attorney to discuss your situation with them. Good luck.
