US Attorney Carmen M. Ortiz, already under fire after the suicide of a prominent computer hacker that her office was prosecuting, came under more criticism Tuesday when her husband rushed to her defense on Twitter with critical postings against the 26-year-old man’s family.

In one tweet posted late Monday, on the eve of Aaron Swartz’s funeral, Thomas J. Dolan, an IBM executive who married Ortiz in July 2011, wrote: “Truly incredible that in their own son’s obit they blame others for his death and make no mention of the 6-month offer.”
