Baton Rouge, Louisiana, Private Investigators

Corporate Investigations for Attorneys

Our private investigation department out of Baton Rouge specializes in corporate investigations on behalf of attorneys who are collecting information and evidence for a case. Investigations may include witness interviews, examination of financial records, employee and management communication research, and even social media investigations. We work with attorneys to verify or disprove claims of fraud or wrongdoing and can even go undercover within workplaces if necessary.

Corporate investigations uncover situations such as theft, embezzlement, blackmail and other corruption, industrial espionage, fraud, cybersecurity threats, piracy, trademark/patent infringement, and more.

Corporate Investigations for Employment Agencies

Large and medium sized employment agencies or staffing agencies place up to thousands of employees into temporary and permanent positions in companies of various sizes and corporate policies. IRS works with these agencies to provide quick and thorough background checks and identity verification for multiple persons on a regular basis. Additionally, for employees covered by the staffing agency’s workers compensation policy and who are injured in their placements, we do workers comp investigations to uncover potential fraud. Call to discuss your situation and we will offer you a consultation to discuss what level of investigation we believe your company needs, so you can avoid overspending on an unnecessarily thorough research endeavor.

Criminal Defense Investigations

We work primarily with solo and small firm criminal defense attorneys to locate witnesses, collect witness statements, reinterview, collect communication and profile evidence, and review interview techniques. Our investigators gather all applicable information and, most importantly, curate and organize it into packages that are comprehensive, searchable, and easy for attorneys to understand quickly.

Child Support and Custody Investigations

In cases of divorce or separation, child custody and financial support investigations can help make certain that the child involved will not only stay safe but will be financially provided for in the foreseeable future.

A parent or court may order a child custody investigator to determine what the child's life experiences are like regarding both parents and with close or extended family relatives. Investigations of parents or relatives can uncover prolonged neglect, child abuse, alcoholism, or drug abuse within the home and/or in sight of the child.

Investigative Research Specialties' (IRS Inc) licensed investigators may use surveillance to determine what happens when a parent or person(s) of concern are with the child. We specialize in providing discreet covert surveillances. In child custody cases our investigators document, photograph and/or video tape abuse, neglect or other evidences which indicates that the child is being mistreated and may be in imminent danger. Our investigators will determine whether a parent or parents indulge in reckless driving, criminal activity, alcoholism, neglect, or other activities which may affect a child's welfare.

Once the surveillance portion of the investigation is complete, IRS Inc Investigators will question the parents; we have them out the appropriate parental documents concerning their parenting style with the child.

Additionally, IRS Inc. Investigators will locate and petition witnesses for the court on behalf of our client.

Evidence and the findings uncovered and provided by IRS Inc Investigators to the attorney carries credibility in court, much more than a parent's accusation, therefore the hiring of an experienced and well qualified professional investigator is critical to your case.
