Our mission is to solve & Clear cases

YOU’VE TRIED EVERYTHING. YOU HAVE SEARCHED HIGH AND LOW. NO ONE HAS LISTENED TO YOU. MAYBE YOU’RE A FAMIY THAT’S SPENT THOUSANDS OF DOLLARS AND GOTTEN NOWHERE. MAYBE YOU’RE AN INVESTIGATOR WHOSE DONE EVERYTHING YOU CAN, BUT STILL THE CASE WON’T CLEAR THE LAST HURDLE.

Often by those who have never done the job themselves, publicly criticize and bash our American law enforcement professionals for what they don’t know, what they didn’t do, what they did do, for mistakes they make, for “dropping the ball,” and the list goes on.

However, please take a minute to consider this: American law enforcement professionals are not privy to top-of-the-line training and equipment as are American sports and entertainment professionals. Until the reallocation of fiscal resources in the United States, nothing will ever change. As long as sports and entertainment are the top priorities of the American people as evidenced in the comparison between the budget for American public safety versus only one professional sports team or professional entertainment tour, the American people will continue to get what they pay for: world-class sports and entertainment and law enforcement reflective of depleted budgets and below-par salaries.
