Criminal Defence 

While all criminal cases do not require the services of a private investigator, in cases that do, the private investigator often becomes one of the most important members of the legal defence team. A private investigator employed by the defence team performs specific tasks in order to prepare an effective defence against criminal charges.

A private investigator will review the police investigation and if required, interview witnesses to discover if there are changes in their statements and to establish if there are any new leads of inquiry. Dion Neill, a licensed private investigator is qualified to assist you with all types of civil and criminal investigations.

Background Checks

If you have any doubts or concerns, before you make a major personal, business or financial commitment, you should consider a discreet background check by a private investigator. The background check will confirm the identity of the individual, criminal history, insolvency information and the ownership of assets.

In a personal matter, a background check may determine if your potential partner is really who they say they are? Have they ever been married, or are they still married?

While some people believe it’s easy to just search and check a person’s name on the internet to find out more about them, that is simply not enough. If you are in doubt or have a suspicion, we can help to uncover the facts.

Pre-Employment Screening

High staff turnover, unsuitable employees and dishonest staff can ultimately cost your company or organisation thousands of dollars in time, money and resources. That’s why it’s important you recruit the right person from the very beginning.

While it is likely that your candidates are presenting themselves honestly, a simple discreet background check by Dion and his associates will help you identify any possible history of dishonesty or pattern of behaviour that is not aligned with your best interests.
