Before a case may be effectively prosecuted, many things must happen on the law enforcement end including, but not limited to, gathering witness statements, examining digital devices, conducting lab testing, collecting video surveillance and photographs, issuing subpoenas for medical and business records, and following up on additional investigative leads. Once the law enforcement investigation is complete, the prosecutor must review and prepare the case to present to the grand jury. Depending on the complexity of the case, this process may take months from the date of offense. While this may be frustrating, it is essential to the prosecutor that all available evidence has been gathered and that the investigation has been thoroughly conducted before proceeding with a criminal case.
