In Texas, if the Legislature has not specified venue for a specific type of crime, then "the proper county for the prosecution of offenses is that in which the offense was committed." Special venue statutes, however, expand the number of counties in which an offense may be prosecuted. These special venue statutes have been enacted for various reasons, such as: the difficulty of proving precisely where the offense was committed; the location where evidence of the crime is found; the effect that a crime may have upon several different counties; the effect that the actor may have upon various counties. Texas venue statutes are a species of codified "substantial contacts" jurisdiction; thus, for venue to lie, the defendant, his conduct, his victim, or the fruits of his crime must have some relationship to the prosecuting county. The Legislature has specified the types of contacts that satisfy this "substantial contacts" threshold for various offenses. Soliz v. State, 97 S.W.3d 137, 141 (Tex. Crim. App. 2003)
