Interview Investigations are services that private investigators with LaSalle Investigations can provide to obtain detailed information about a person or a business. Investigators with LaSalle Investigations know what questions to ask in an investigation interview. We typically follow a line of questions based on the investigation. We also either listen to our client’s needs and develop a list of questions based on the scenario or we follow a list provided by the client. We also ask key questions based on the answers provided by the subject. LaSalle Investigators have completed training in some of the most advanced Interview and Interrogation training in the world.
