Protecting The Innocent From Government Prosecutors


Defense Investigation Group, Inc. is based in Beverly Hills
California and owned by Robert P. Royce. We specialize in
criminal defense investigations for major crimes. Our private
investigation firm is well known and respected by attorneys and
judges through-out Los Angeles County. We have recently open
our services to attorneys and law professionals in the state of
Arizona. Our Scottsdale office will be opening soon.

Our company understands the government's methods of
attacking all citizens including the rich, the poor and minorities
of this great country. We believe that everyone has the absolute
right to a fair trial and an even playing field with the
government. We do not allow the government to dissuade us
from our goal of finding the truth.

Our firm accesses the highest rated private databases that
assist in tracking and locating witnesses. We have located more
witnesses in the government's witness protection program than
any other California and Arizona private investigator.

We maintain professional memberships in local, state and
national criminal defense investigator associations.  Our
investigators attend at least three training seminars a year to be
updated on all laws, forensic techniques and investigation
updates.  

We are also the defense investigation firm that police officers
turn to when they get indicted, arrested or charged with felony
crimes on duty or off duty. They know we are the bull dogs of
criminal defense investigators. Thats why they want us on their
case and they should know!

Criminal defense investigation is a highly specialized discipline
within itself and therefore requires education, experience,
training and research suited to its own needs. Our firm is one of
the few investigation firms in Arizona that specializes only in
criminal defense.
