OSIG investigators are experienced in the following areas: assault & battery, indecent assault & battery, DUI cases, breaking & entering, theft/robbery, fraud, & post-conviction appeals. OSIG conducts competent & detailed criminal defense investigations by working closely with defense attorneys to determine the scope of each investigation. We then tailor our investigation for the unique circumstances of every case. OSIG is always there to fully help plan, support & execute the investigator’s role in the trial & assist the client in trial preparation. OSIG can also offer pretrial process serving & witness transportation. OSIG is able to conduct aspects of Civil and Criminal investigations to include, but not limited to, records searches, social media mining, data base searches, witness interviews. OSIG assists lawyers, individuals and businesses in the gathering of information and evidence for a successful resolution in court or their own personal knowledge. Legal investigations are those cases that are being investigated & prepared to go to trial. Attorneys & law firms representing clients with civil, criminal, corporate, copyright, environmental, probate, domestic, governmental, international & property concerns can depend on a investigator for prompt & professional legal investigations.
  • Our investigators have the attitude, competence, demeanor & determination to assist you & your clientele. The absolute best outcome in legal cases that appear to be headed for court is a successful resolution prior to a trial. Our investigators along with the client, establish an investigative theme based on the theory of liability &/or the theory of defense to effectively investigate legal matters. OSIG concentrates on the investigation theme to compliment the theories that have been developed and established. We focus in on that during the investigation in order to help bring the matter to an amicable resolution.  


Witness Locations & Statements

  • Interviewing & obtaining recorded or signed written statements from witnesses, claimants, insureds, subjects & other individuals is the very essence the nature of the investigative business & must be successfully accomplished on a priority basis. Major areas covered include eyewitness accounts of incidents & accidents, liability questions, insurance coverage issues, fraud, social media accounts, reputation & character, due diligence, testimony & pre-trial preparation, general information, background data & employer/employee statements.  Statements are usually digitally recorded & can be emailed to the client upon completion. Transcription of statements is accomplished upon request. Reporting of interviews & statements are included in abstract form within the investigation report, in investigator’s notes, or verbally communicated depending upon the client’s instructions. OSIG has years of experience of experience in interviewing techniques & assessing the truthfulness, character & credibility of witnesses. Our clients have been extremely happy with the content & results of our statements as they are detailed in content & focus on the facts of the case.
