Ed Martin grew up in New Orleans, Louisiana. In 1968 he earned his degree in accounting from Southeastern Louisiana College (now the University of Southeastern Louisiana). Following graduation, Ed spent a year with a New Orleans CPA firm and then applied for a position with the Intelligence Division of the IRS. He accepted the job and from August 1969 to February 1970 he trained in federal law enforcement in Washington, DC. After returning to New Orleans he became part of the DOJ Strike Force team that investigated District Attorney Jim Garrison and the New Orleans Police Department for public bribery by the local pinball industry.

In 1975, Martin and his family moved to Austin, Texas where his career continued. After reaching senior agent status he became a lead agent in the investigation and prosecution of income tax evasion cases and of multiple fraud investigations.

Martin resigned from the US Treasury Department in 1984 and worked as a Supervising Examiner for the Texas State Securities Board in Austin. This experience allowed Martin to become adept in broader definitions of fraud: Ponzi schemes (John Colgin–1985), oil and gas fraud, and securities fraud.

In 1991, Martin returned to the IRS Criminal Investigation Division as a Special Agent to investigate fraud and money laundering cases. Some of the cases Martin handled during this period included: the employee leasing company Ralph Kirkley, Inc. (1996), the advanced fee scheme of William Fourie (1996-1998), the Ponzi schemes of Russell Erxleben (1998-1999), and Brian Stearns (1999-2000). Martin was also the lead agent and instrumental in solving the 5-year-old mystery of what happened to Madalyn Murray O’Hair and her two adult children (1997-2000). After the trial of one of the criminals convicted in the O’Hair case, the Austin Chronicle stated: “If not for the methodical investigation of Special Agent Ed Martin and the FBI they (Gary Karr and David Waters) would have gotten away with murder.”

After nearly twenty-six years Martin retired. He was presented with an award for his “Dedication to the Cause of Law Enforcement” by the US Attorney’s Office in Austin and he was nominated for the FBI’s Director’s Award. In 2002, Martin received the Law Enforcement Circle of Excellence Award from the Central Texas 100 Club and in June 2002 received the “Service Above Self Award” for the Austin Rotary Clubs.

Martin has been interviewed on American Justice, American Chronicles, TruTV, A&E, and Discovery for his investigation of the disappearance and murder of Madalyn Murray O’Hair and her children.

Since retiring in October 2001, Martin launched Sage Investigations, LLC a Private Investigation firm where he investigates various cases including forensic accounting, income tax defense, litigation support, corporate investigations, and anything related to following money, including fraud and embezzlement and Ponzi schemes. In 2002, Martin joined the Texas Association of Licensed Investigators (TALI), and later in 2006 TALI awarded Martin a Meritorious Service Award for Investigative Excellence. In 2007 Martin tested and received the Texas Board Certified Investigator (TBCI) designation from TALI.

In 2006, Martin founded Cynic, Inc. and launched DIO, proprietary software for the investigation of complex fraud investigations, which takes advantage of data mining technology, document scanning, OCR capabilities, organizational services, and reporting for the legal community.

Sage’s team of former IRS Criminal Investigators, Certified Public Accountants, and former FBI investigators, are solely committed to providing results that reflect the truth.

Within those markets, Sage represents their clients in civil and criminal matters involving fraud, embezzlement, Ponzi schemes, and business disputes that involve following money trails and developing evidence to prove the client’s case on the plaintiff or defense mode.

Jason Slick grew up in Alvin, TX. He earned his degree in mathematics and computer science from Texas State University in 1998. His early career experiences as a software engineer gave him the skills to become a world-class forensic financial investigator at Sage Investigations. At Sage, Jason’s diligence, productivity, and years of experience in mathematics and computer science make him the natural choice for the most complicated cases and large value asset tracing. He also is tasked with investigating databases, big data sets, cryptocurrency, custom point-of-sale systems, and all forms of digital data. His reports clearly communicate the essential evidence and are instrumental in proving financial narrative.

Not only does he excel in his work on cases, but Jason also developed the algorithms and essence of Sage’s case management software (DIO). This software allows the company’s reports to be far more accurate than those of any competing investigator. His software is based on the principle of following the money and does not rely on any simple accounting tricks. Furthermore, Jason, his software and team are both more precise, analytical and efficient, meaning lower costs for Sage’s clients.
