On July 21, 2022, Guadalupe County Sheriff's K9 Corporal Dustin Crawford was working criminal interdiction on IH 10 near Mile Marker 621, Guadalupe County, Texas.  Cpl Crawford observed the vehicle traveling eastbound on Interstate Highway 10. The driver of the vehicle committed a traffic violation at which point Cpl Crawford conducted a traffic stop. Cpl Crawford spoke with the driver, who was identified as Ana Laura Hernandez, from Laredo, Texas. Hernandez's juvenile son was also present inside the vehicle. As Cpl Crawford spoke with Hernandez, Cpl Crawford observed Hernandez's behavior to be suspicious. Cpl Crawford asked Hernandez for consent to search the vehicle and was granted consent. Cpl Crawford observed a vehicle battery on the back seat floorboard behind the front passenger seat. Cpl Crawford utilized his K9 partner, "Eddie" and conducted a free air sniff around the vehicle battery. K9 Eddie alerted to the vehicle battery. Cpl Crawford searched the vehicle battery and found 4, individually packaged, bundles wrapped in plastic. Cpl Crawford recognized the packaging to be consistent with narcotics packaging. The bundles contained a substance that field tested positive for Fentanyl. The audit weight of the narcotics was 4.5 kilograms. Hernandez was placed in custody and booked in to the Guadalupe County Jail for the offense of Manufacture or Delivery of a Controlled Substance in Penalty Group 1 B greater than 400 Grams (Fentanyl). The street value of the Fentanyl seized by Cpl Crawford is estimated to be worth over $100,000.  The child was released to a relative. This case will be forwarded to Guadalupe County Attorney's Office for prosecutorial review.
