SAN JOSE, Calif.—Lawyers for Ramesh “Sunny” Balwani called their second and final witness and rested their brief defense of the onetime Theranos Inc. executive charged with a dozen counts of criminal fraud.
Mr. Balwani didn’t testify in his own defense. Thursday’s testimony from technical consultant Richard Sonnier brings the trial, which follows the conviction of Theranos founder and Chief Executive Elizabeth Holmes in January, nearer to completion. Mr. Sonnier’s technical testimony about a database followed testimony from an Arizona physician, who backtracked some of her support for Theranos on the stand.
