Jeff Van Horn

Jeff Van Horn was raised in Caldwell County, Texas and graduated from the University of Texas at Austin with a B.A. in psychology in 1969. Van Horn received his J.D. degree from the University of Texas School of Law in 1973. He was admitted to the Texas Bar that same year and, prior to his work as a prosecutor, was engaged in private practice in Jasper and Luling.

He served as Criminal District Attorney of Caldwell County from 1981 to 1990, after serving as Assistant District Attorney for Caldwell and Comal Counties and as Justice of the Peace for Precinct 2 of Caldwell County.

He has served as a Director of the Texas District & County Attorneys Association, as a member of the Ad Hoc Committee to Revise the Code of Criminal Procedure, and as President of the Caldwell County Bar Association. He was an organizer of the Caldwell County Crimestoppers program, an organizer of the Lockhart Against Drugs program, and the Director of the Hays-Blanco-Caldwell Council on Alcoholism & Drug Abuse.

Van Horn joined the office as an Assistant State Prosecuting Attorney in 1991 and was appointed as State Prosecuting Attorney in 2007 through his retirement in December 2010.  That same year, he was honored by the Criminal Justice Division of the State Bar of Texas as the Texas Prosecutor of the Year.

Van Horn has had a number of notable successes while representing the State before the Court of Criminal Appeals. In Standefer v. State, 59 S.W.3d 177 (Tex. Crim. App. 2001), the Court clarified the law relating to the definition and propriety of commitment questions during voir dire examination, and in Hernandez v. State, 988 S.W.2d 770 (Tex. Crim. App. 1999), the Court abandoned the Duffy standard in favor of the Strickland standard for evaluation of ineffective assistance of counsel claims at noncapital sentencing proceedings.

Van Horn led the successful effort in Ex parte Lewis, 219 S.W.3d 335 (Tex. Crim. App. 2007), to persuade the Court of Criminal Appeals to overrule its decision in Bauder v. State, 921 S.W.2d 696 (Tex. Crim. App. 1996). He was also instrumental in the Court's decision not to apply the Bauder principle to appellate reversals due to prosecutorial misconduct after full trial on the merits, in a pair of decisions, Ex parte Davis, 957 S.W.2d 9 (Tex. Crim. App. 1997), and Ex parte Mitchell, 977 S.W.2d 575 (Tex. Crim. App. 1997). And in Ex parte Edone, 740 S.W.2d 446 (Tex. Crim. App. 1987), the Court of Criminal Appeals overruled its previous decision in Ex parte Port and held that the violation of a court order requiring a witness to answer before a grand jury constitutes contempt of court.

Van Horn died May 6, 2023, in San Marcos, Texas.  See Jeffrey L. Van Horn's Obituary.
