Marcus Ruiz
INVESTIGATION

As an investigator with Mastantuono Coffee & Thomas, Marcus Ruiz has a robust role as part of the MC&T defense team. He routinely reviews police reports as a starting point for more in-depth investigation, whether it is related to an inaccuracy or missing information. Marcus conducts follow-up witness interviews, completes in person scene visits, obtains medical or business records, and reviews cell phone data. Administratively, he facilitates our electronic discovery procedure and maintains those files.

Marcus’ experience as an investigator is derived from his service as a U.S. Marine Corporal from 2003 to 2009, including two tours of active combat duty in Iraq. During that time, he conducted investigations as part of the Stability and Support Operations. In that role, Marcus conducted surveillance of targets, gathered intelligence from regular patrols and raids, interviewed local citizens, arrested and interrogated suspects, and generated written reports of all work in this capacity.

Marcus is also skilled in investigating internal corporate compliance complaints and white collar crime. He spent 5 years in an auditing position with a Fortune 500 company that required him to ensure international factory compliance with company terms of engagement and local laws. He then transitioned to security and supply chain compliance, which required him to follow all US Customs regulations and complete internal division audits for compliance.

Also fluent in Spanish, Marcus is an asset to our defense team since joining us in 2010. He spent five years as MC&T’s investigator while he completed his degree at University of Wisconsin-Milwaukee after he returned from war. After five years in corporate compliance, Marcus rejoined MC&T in 2021. Over the years, he has testified in litigation on behalf of our clients in both state and federal courts.  

Marcus is also an expert rifleman, which is the highest designation in the USMC for shooting, and he served as his platoon designated marksman. He continues to be an avid shooter, and provides firearms expertise to the MC&T team. Marcus regularly attends firearms trainings, teaches firearms courses, and is sponsored by a rifle barrel company for his shooting.
