Consanguinity means that two people are blood related. Section 20.05(d) of the Smuggling of Persons offense states that a driver has an affirmative defense if the driver is related to the individual allegedly being smuggled by a “second degree of consanguinity.” A person is within the second degree of consanguinity to another if there is a relationship such as a child/parent relationship, brother/sister relationship, or grandchild/grandparent relationship.
