We conduct a complete and thorough investigation of all types of incidents. If a police investigation was already conducted, we will meticulously review all reports, documents and evidence for omissions and errors. We will do all we can to assist our client in their defense. Frequently, criminal investigations are riddled with mistakes and are not performed in a professional manner. Unfortunately, whether it’s a lack of experience, training or laziness, poor investigation practices often result in an abysmal outcome for all parties involved. We analysis all the data we uncover and provide our findings in a final report. It’s common for us to find new witnesses and undiscovered evidence beneficial for our client, once we initiate our investigation.
