I received a call from 239-938-7601 this morning at 9:16am saying that there was a criminal case filed against me, case #KH76295 and that I needed to get my attorney and call 202-899-9017 immediately. If I didn't return their call, the case against me would proceed rapidly. Needless to say, I didn't call the number, nor will I.
