Services
We are a full service private investigative agency located in Northeast Wisconsin. We network with other investigators that adhere to the same professionalism as our agency which enables us to cover the entire state. In many cases we find that our clients will request us to still handle their cases due to the personalized attention that we provide to them.
The office of Magnum Investigations Plus has the experience to work well with Attorneys and Paralegals to assist them in meeting their specifications with thorough report writing, fact finding and video documentation as needed. We at Magnum Investigations Plus pride ourselves on doing the best job possible for your office, and meeting your requests to the best of our ability.
MIP even was able to locate and collect collateral that was being wrongfully held by tow yards, convincing the companies to release the vehicles. That is a task our attorney couldn't even get accomplished. MIP is well informed of WI collateral recovery laws as well as Indian Reservation laws. I was very impressed on how fast they are able to recover property.
This also guarantees that our investigators are getting continuing training and up to date information on technology and laws. The Professional Association of Wisconsin Licensed Investigators, Inc represents the highest principles of ethical conduct in the private investigator profession. Our good friend, former NYPD officer and President of International Cops for Christ, Mike DiSanza has now gone to be with the Lord and is deeply missed.

My spouse was having an affair and claimed to end it. My instincts told me otherwise. I called Chris at Magnum Investigations. He spent a great deal of time answering question, educating me and developing a strategy. Chris is ethical, moral and compassionate: qualities needed when dealing with the sensitive issues of infidelity. In one conversation, I knew I was talking to someone result driven by what is wrong and wrong.

He gave me with a wealth of information, patiently answered questions and was transparent about cost so that there were no surprises. During surveillance, I was kept informed every step of the way. He made me and my case top priority. It took Chris just 1 day to catch my spouse cheating and gave me concrete evidence I needed. Chris is a seasoned investigator who provided me with results, information and confidence to file for divorce. I highly recommended Magnum Investigations as Chris and his team will not disappoint! Excellent work!

I called Magnum with some concerns that my house may have been bugged. It was such a pleasure to talk with Chris, who took the time to understand my situation, explain the various options (including pros and cons) and give me advice. Instead of pushing his services, he was honest and kind and suggested cost effective alternatives, which would be a lot less expensive than his services. Chris is definitely a gem and I would wholeheartedly use him in future and recommend him to anyone!

Chris was excellent. I came to find Magnum Investigations through a general Google search, and after another company would not return my phone calls when I attempted to hire them. Things happen for a reason because I found Chris. He promptly returned my call despite his being away on vacation. He kept me updated in real time during his active surveillance.

He updated me in detail after each period of surveillance. He returned my texts, phone calls and emails promptly. This was all over a period of 2 months and several dates of surveillance. He was always quick to respond. His reports were thorough and irrefutable. Most importantly, Chris was personally invested and I didn't feel like just another client or customer.

He listened to my concerns and got to know me personally. I felt that he had my best interests in mind and took the time to get to know me. My entire dealings with him were great and I would hire Chris again. I would also highly recommend his service. PS. His services yielded a positive outcome in my custody dispute. There is no price tag for that.

Magnum Investigations far exceeded my expectations and I will happily use them for all future investigative needs. They're the best in the business and work hard around your schedule as well as do whatever it takes to get the job done. Very pleased with their professionalism and level of commitment to help us with our custody case. They're not the cheapest but is cheap what you want when it comes to the safety of your loved ones or do you want the best? Do yourself a favor and just hire them. Well worth the money! Thank you for everything, Chris!

YOU GET WHAT YOU PAY FOR! And Chris and his team at Magnum Investigations are worth every penny. Not only did Chris respond to my inquiry right away. He had a team ready to go the very next day to get the results and, more importantly, the proof I needed to make the right decisions in my case. Chris and his team are not the cheapest around, but then again, comparing any other investigation team to Magnum in our region, is like comparing the dollar menu at Micky D's to a filet mignon at a 5 star restaurant.

In other words, there is no comparison. Thank you Chris for, not only your professionalism and quick work, but for your compassion and empathy during what was a very difficult time in my life.

I would highly recommend Magnum Investigations for effective, professional, top notch service. Chris took the extra time to thoroughly evaluate the situation in order to devise a successful strategy. I especially appreciated his advice, as a straight shooter, and his personal counseling during a most difficult time for me. Chris is a seasoned investigator with a law enforcement background, and his particular expertise with cheating spouses, including their relative behavior patterns, proved to be invaluable. Thanks for the A+ service!

After reading some of the other reviews on Magnum Investigations I've decided to speak from my heart with a review about Chris Halscheid and his company. I hired this man to reveal the ugly truths that brought evidence and closure to my marital situation. Not only did Chris provide everything I needed, he went above and beyond to go the extra mile producing more than I had requested.

The character and professionalism of Chris is driven by his passion to uncover the ugly truths of wrong doers. Chris is an extremely compassionate man who counseled me through every step of the painfully revealing investigation. I can't thank him enough for his abundance of patience and compassion to my well being, he treated me as if I was a member of his family. I consider Chris a true friend now. For anyone seeking discovery to suspicious marital activities, I am highly recommending Chris and his services.

Chris and his team exceeded my expectations every step of the way. His instincts concerning when and where things would take place are incredible. He was always right. I was continually impressed with his organizations professionalism. Not only was I pleased with their performance but Chris constantly checked on how I was doing and my mental state. He was a great sounding board throughout the process. I can't say enough great things about Chris and his company!
