Skip Tracing | Witness Location - Locating persons that
have pertinent information regarding your case can be a
difficult task. CSISs investigators have the tools and
expertise to locate them.

Photo | Video Surveillance - CSISs investigators have
decades of surveillance experience using state of the art
technology to capture our subject's activities.

Activity Check - After a claimant accepts a settlement or is

conversation. Through in person activity checks CSISs
investigators will confirm the claimant is alive and receiving
their benefit, as well as determine if the recipient's claim is
suspicious and warrants further investigation.
