Criminal defense cases require the necessary burden of proof beyond reasonable doubt. The Defense team must show that:

a) the allegations, testimony and evidence is false or unreliable
b) why the client/defendant is falsely being charged and
c) how the false charges were developed

Criminal defense cases require special care and the confidence in a team of professionals to assist you.

Astute Criminal Investigation's managing investigators have a combined 70 years of law enforcement & investigation experience. ACI Private Investigators have handled everything from minor theft cases, to sexual assaults, to homicides investigations. Founders, Claude & Kim Ammons are Board Certified Criminal Defense Specialist and utilize the Component Method taught by Nationally Recognized Author and Criminal Defense Investigation Instructor, Brandon A. Perron. They have experience in obtaining statements from reluctant witnesses, criminal profiling and mitigating possible damages.

ACI has a multi-racial & multi-gender staff which allows us to utilize the most appropriate Investigator for certain aspects of the investigation. Not every witness is going to open up to a male investigator with a law enforcement background, appearance or vernacular. Female Investigators are great Private Investigators for multiple reasons, but being tenacious, inquisitive & unassuming/non-threatening are the most intangible assets in our opinion. Some witnesses need a woman's touch. Some witnesses will not open up to a Caucasian female Investigator, but they will open up to a Hispanic male’s inquiries. Some investigations will require a man's presence, while others Investigations will require a feminine touch. Rest assured that while our Investigators have their dominant skill sets, they are all more than competent in the many traits needed to be a complete and successful investigator. Our Investigators are trained and are required to excel in obtaining information over the phone & in person, must be knowledgeable in computer research & data mining and proficient in locating people who usually don’t want to be found. Nonetheless, our Investigator’s dominant skill set are always utilized & tailored for each case for maximum results.
