OPINION
On appellant’s motion for rehearing, this court’s opinion of June 13, 1991, is withdrawn. The following opinion is substituted therefor, and appellant’s motion for rehearing is overruled.
Appellant was convicted by a jury of possession of marihuana in a usable quantity of more than two hundred and less than two thousand pounds. The court assessed a sentence of fifteen years in prison and a fine of $1,000.00. In one point of error, appellant alleges insufficient affirmative links to sustain the jury finding that appellant intentionally and knowingly possessed the drugs. We affirm.
Raymundo Elizondo Alvarez was one of a group of Mexican nationals arrested near Houston on January 17, 1989, during the culmination of a three-day undercover and surveillance operation conducted by combined forces of the Department of Public Safety, Texas Rangers and several county sheriff’s departments. On January 15 D.P.S. officers were tipped by an informant that a white tanker trailer loaded with contraband would travel from a point near appellant’s residence, located outside Rio Grande City, to Houston.
The tanker was spotted and tracked by aircraft and automobiles as it moved along its route throughout the day of January 16. It was followed, preceded or met from time to time by a blue Chevrolet pickup and a red Pontiac automobile. The pickup had originally been observed by officers in the vicinity of appellant's home. Testimony at trial established the pickup was “running counter surveillance” or conducting “heat runs” in an effort to distract the attention of peace officers or to expose their presence along the route. That tactic involved the pickup passing the tanker and proceeding ahead for ten to fifteen miles in order to detect any police surveillance. The pickup would then pull over, wait for the tanker to pass, fall in behind and repeat the operation.
Testimony from several peace officers who participated in the surveillance firmly established appellant’s positive identification as a passenger in the pickup during stops made at Freer, Berclaire and Sugar Land. Alvarez was observed the evening of January 16 at the scene of the parked tanker near Sugar Land. He left the tanker to make a series of telephone calls at a nearby service station phone booth, returned to the tanker’s location, and subsequently returned to the public phone to make and receive additional calls. The tanker, red Pontiac and the pickup carrying appellant then convoyed to a motel in southwest Houston. The pickup left that location and travelled that evening to another motel to establish contact with additional members of the group traveling in a Ford Thunderbird.
On the morning of January 17 Alvarez reappeared at the motel where the tanker was located with another codefendant in a green Subaru automobile. Other group *224 members had already arrived in the Thunderbird. After they checked out of the motel, one group member jump-started the tanker and the conspirators proceeded in the Thunderbird, Subaru and tanker to a secluded location east of Houston.
Throughout the remainder of the day law enforcement officers maintained their vigil in the area where the tanker was parked. They observed appellant in the Thunderbird as it travelled to and from the scene. D.P.S. officers testified they observed two individuals unloading marihuana from the tanker and placing it in other vehicles. The group’s activities were terminated later that afternoon when appellant and code-fendants were arrested as they travelled in the Thunderbird, accompanying a U-Haul loaded with 1059 pounds of marihuana.
When reviewing sufficiency of the evidence this court must determine whether, after viewing the evidence in the light most favorable to the prosecution, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.
Jackson v. Virginia,
While mere presence at the scene of the crime is insufficient to prove that a person is a party to the crime, it is a circumstance tending to prove guilt, which, when combined with other facts, may suffice to show that the accused is a participant.
Beardsley v. State,
The proof required of the State to establish unlawful possession of a controlled substance is that: (1) the accused exercised care, control or management over the contraband, and (2) the accused knew the matter possessed was contraband.
Sinor v. State,
Knowledge that the contraband was in fact a controlled substance can be proven when the evidence
affirmatively links
the accused to the contraband “in such a manner and to such an extent that a reasonable inference may arise that
the accused knew of the contraband’s existence and its whereabouts.’’ Foster v. State,
The facts and circumstances of this case establish that appellant voluntarily stayed within close physical proximity to at least 1059 pounds of contraband, travelling with the drugs over hundreds of miles and through a time period of at least two days. A rational trier of fact could reasonably infer from such evidence that appellant’s actions in safeguarding, protecting and *225 handling the load indicated his knowledge of its existence and composition.
When drawing the inference that appellant was not simply present at the crime scene but exercised actual care, control and management of the contraband, triers of fact must consider the totality of circumstances, including the presence of such a quantity of narcotics and appellant’s consistent pattern of behavior.
See Oaks,
Appellant urges us to consider this case in light of
Watson v. State,
In the present case appellant guarded the drugs by maintaining a continuous pattern of counter-surveillance over hundreds of miles and several days. He was observed making furtive telephone calls that triggered other activities by group members.
Appellant also argues that an unpublished opinion of this court controls our decision. Unpublished opinions may not be cited as authority. Tex.R.App.P. 90(i).
A conviction based on circumstantial evidence cannot be sustained if the circumstances do not exclude every other reasonable hypothesis except that of the defendant’s guilt.
Oaks v. State,
Accordingly, the judgment of the trial court is affirmed.
