Fraud-Case Closed

A man was claiming Workers' Compensation for a back injury. After covertly receiving information that he was going to go hunting the next morning, Investigator Cook set up surveillance at 2:00 a.m. and followed him and his crew to the mountains several hours away from his residence.

After determining his camp location, the Fraud Investigator prepared himself and was able to low crawl through the Colorado woods, lay perfectly still for hours and was able to obtain video proof as the subject violated his work restrictions.

Infidelity-Case Closed

A dedicated wife and mother feared that her husband was cheating on her. The team at Nebula Investigations learned that the man was going to be staying at a luxury hotel in Colorado Springs. The man and his new girlfriend were located and surveillance was conducted. Video evidence was obtained and the husband was exposed. This man and his girlfriend were so afraid of getting caught, they would ride the elevators up and down just to change clothing in an attempt to hide their identities. They would, at times, take different elevators and stairs separately and then meet up in another location together. Our PI's, with covert surveillance cameras and unparalleled skills, were able to keep track of the couple and report all of this information back to our client.

accidental death-Case Closed

A young man fell approximately six (6) feet from a scaffold and tragically died. After several days of investigation and dozens of interviews, it was determined that multiple safety violations had knowingly occurred previous to this preventable death. Investigator DJ Cook read hundreds of pages of policies and procedures, photographed the entire area, secured the cooperation of the company involved, worked flawlessly with other agencies and helped the family understand what had happened. This case is an example of safety violations that were not only occurring on the day of the incident, but had become a standard practice prior to this unnecessary loss of life.

Child support-Case Closed

A lady contacted Nebula Investigations and was concerned that her ex-husband was not paying child support because he claimed he was not working because of an injury. Our client was having a difficult time financially ever since her husband left her and the kids for another woman. Surveillance was conducted and we uncovered the truth. The ex-husband was working a full-time job, living comfortably and it appeared that he had no injury that would prevent him from working and providing child support for the family he abandoned. Evidence was obtained and submitted to her lawyer.
