- Successfully represented a Texas man prosecuted for capital murder. Prior to this trial, the district attorney’s office had a 75-0 record in capital murder trials. After the week-long trial, the Court declared a mistrial based on the jury being deadlocked after two days of deliberations. At the time of the mistrial, the jurors (including the alternate) were split 8-5 in favor of a not guilty verdict. Following the trial, the State dropped all charges against the client. (State of Texas v. Johnson)

- Obtained a not guilty verdict for a Houston university professor falsely accused of assaulting a female student. (State of Texas vs. Yorke)
- Achieved a not guilty verdict for an employee of a Fortune 100 company prosecuted for engaging in an embezzlement scheme. The client had given three separate confessions to authorities. Todd established the confessions were coerced and false. (State of Texas v. Petrie)
- Won a jury verdict for the mother of a minor child in a two-week child custody jury trial. The Court-appointed ad litem attorney representing the minor child, as well as the father of the child, sought to divest the client of custody rights. The client nevertheless prevailed on all issues. Todd stepped into the case ten days before trial. (In re Xochiitil Trejo Whetzel)
