Legal Support Investigative Service is comprised of a team of highly skilled and experienced private investigators. Our team has a diverse background in law enforcement, the military, and private investigation.
We have in-depth training in Torts and Civil Litigation from an ABA-approved college Paralegal Program. Additionally, we have extensive training in Interviewing techniques, investigations, and incident scene documentation.
“Randall assisted our firm in the trial of a complex personal injury case arising out of a criminal battery. Numerous witnesses had provided multiple, often conflicting statements to the responding police officers, and later to detectives, an insurance investigator, and in depositions.
We employed Randall for both his Paralegal and Investigative expertise to review, compare and contrast all statements and deposition testimony. He found repeated contradictions in the defense witness statements, allowing me to effectively attack the credibility of these defense witnesses at trial. Additionally, Randall took photographs of the scene and created a scene diagram which we enlarged for use in trial which visually demonstrated the witness locations with measured distances from the incident, supporting our case.
Randall's work in both contexts was exceptional, as was his reliability, integrity and professionalism. I would not hesitate to recommend Randall in either capacity in any civil or criminal litigation.”

Our client was severely injured when a new ATV caught fire. Our extensive investigation on the product, product history, recalls, internet documentation, etc., gave the law firm the evidence needed to settle for just under 8 figures.

Witness interviews can be very delicate in nature, requiring a sensitive but direct approach. Once we conduct a witness interview, we generate a declaration to be reviewed & signed by the witness.

Our comprehensive background investigations can help you make informed decisions regarding the defendant, witnesses, and sometimes even our own client.
Possessing the investigative and technical skill to recreate an eyewitness perspective gives the law firm and court the opportunity to see what a witness may or may not have been able to see from their perspective in the form of depth-of-field appropriate DSLR photographs.

When an attorney service fails, we frequently handle locating and serving difficult witnesses and defendants. Our Proof of Service is accompanied by a photograph of the party served. In extreme cases, we provide a declaration of due diligence in support of Service by Publication.
