Tax fraud case

HOUSTON — In the largest alleged tax-evasion scheme in U.S. history, a federal judge in Houston ruled 80-year-old software billionaire Robert Brockman is competent to stand trial on charges although he has Parkinson’s disease, possibly Alzheimer’s, and is “suffering from some degree of age-related cognitive decline.” Brockman, according to the court, is “an extremely intelligent person with both a high cognitive reserve and history of malingering for secondary gain.”
