If your idea of the perfect night involves alibis, motives, and true crime podcasters, then this is the event you’ve been waiting for.

The Difference

I never take a case that I personally feel can’t be resolved.  That’s what makes me different. Through a comprehensive consultation, I will be able to understand the ins and outs of your case. This information will help develop a powerful strategy, or provide you with referrals to experts who can provide you with the services you need.
