OPINION
Opinion by Justice GARZA.
A jury convicted Leviyas Jamail Clayton of murder, and he was sentenced to thirty years' imprisonment. Clayton now appeals his conviction, arguing that the evidence was legally and factually insufficient to prove he committed murder. Because we conclude that the evidence is legally insufficient, we reverse the judgment of the trial court and enter a judgment of acquittal.

I.
At approximately noon on June 14, 2001, Angela Davis, an employee of the City of Houston Animal Control Department, stopped near the entrance to Brock Park in Houston to aid the driver of a pickup *256 truck which had overturned and landed in a ditch. Davis's partner, Glen Hudson, was in another vehicle behind her and stopped as well. After being on the side of the road for roughly ten to twenty-five minutes, Davis looked off into the park and noticed something peculiar waving in the air. She drove over to investigate and discovered James Playnonero laying in the grass, bleeding. Davis called 911, but Playnonero died about ten minutes later.
Playnonero was found next to a white 1995 Toyota Avalon, which had been rammed into a tree. The trunk and rear passenger door of the car were open. A tire rod was found in the driver's seat, and a bloodied tire iron was found in the car's trunk. The fuel intake manifold was open and had singe marks around it. Police discovered a wad of burned paper lodged in the manifold and suspected that someone had tried to destroy the vehicle by igniting the gas tank. The vehicle's backseat and rear floorboard were soaked with blood, and blood was found on the vehicle's exterior. A two-foot wide trail of blood led from the backseat of the car to Playnonero's body, indicating that Playnonero might have crawled from the backseat of the car to the spot where Davis found him.
The medical examiner determined that Playnonero's death resulted from loss of blood caused by multiple gunshot wounds. According to the examiner's autopsy report, Playnonero was shot eight times: in both legs, the forearms, abdomen, penis, and neck.
The ensuing police investigation yielded few leads. No eyewitnesses were identified. Police forensics could not determine whether the gunshot wounds were inflicted by a single gun or multiple guns, and no weapons were ever linked to the shooting. In addition, the police could not determine whether Playnonero was shot inside or outside of the car or whether the shooting took place in the park or at some other location.
The fingerprints of two individuals other than Playnonero were discovered inside the vehicle. The first set of prints belonged to Angel Ayala, the owner of the vehicle. Ayala was initially investigated for the murder but was ultimately cleared of suspicion. Apparently, he had allowed Playnonero to borrow the car on the morning of the murder, and Playnonero never returned it.
The second set of prints belonged to appellant. They were found on the vehicle's steering wheel and gear shift and on the middle console between the front seats of the car. The prints were what forensic experts call "transfer prints." They resulted from appellant touching objects in the car with blood on his hands. The blood belonged to Playnonero.
A warrant was issued for appellant's arrest, and appellant was ultimately indicted for the murder. At trial, the State offered no evidence other than the bloody fingerprints to connect appellant to Playnonero and the murder. A police officer testified that Playnonero was involved in the illegal drug trade. The officer speculated that the shooting resulted from a drug deal gone bad. No other explanation for the murder or connection between appellant and the victim was offered.
At trial, appellant took the stand in his defense. He testified that on the morning the murder occurred, he drove to Brock Park to visit a female acquaintance named Tiffany Woods. The couple had planned to meet at the park at noon. As he approached the park's entrance, appellant observed a "newer model" blue car rapidly exit the park. After he entered the park, appellant looked for his friend but did not see her. He spotted a white Avalon with its trunk and rear passenger door open. *257 The vehicle was rammed against a tree and its wheels were spinning. Appellant exited his vehicle and approached the Avalon. As he drew closer, he saw a man sitting in the backseat with his hand hanging outside the vehicle. The backseat was "full of blood." Concerned for the man, appellant grasped the man's hand with his hands. He got into the driver's seat and tried to drive the car back onto the street, but the car was stuck in mud and would not move. Appellant put the car into neutral gear. He then heard a loud noise and saw a pickup truck traveling at a high rate of speed. The truck overturned and landed in a nearby ditch. This frightened appellant and he fled. He drove a few miles to his home, where he went to his room and cried. He never called the police and never told anyone about what happened. After being arrested, appellant maintained that he did not know Playnonero and had never seen him before the morning the murder occurred.

II.
When reviewing the legal sufficiency of evidence, we view the evidence in the light most favorable to the verdict to determine whether any rational trier of fact could have found the essential elements of the offense beyond a reasonable doubt. Jackson v. Virginia, 443 U.S. 307, 319, 99 S.Ct. 2781, 61 L.Ed.2d 560 (1979); Sanders v. State, 119 S.W.3d 818, 820 (Tex.Crim.App.2003). We are not fact finders; our role is that of a due process safeguard, ensuring only the rationality of the trier of fact's finding of the essential elements of the offense beyond a reasonable doubt. See Moreno v. State, 755 S.W.2d 866, 867 (Tex.Crim.App.1988). In purely circumstantial cases such as this, it is unnecessary for every fact to point directly and independently to appellant's guilt; it is enough if the conclusion is warranted by the combined and cumulative force of all the incriminating circumstances. See Johnson v. State, 871 S.W.2d 183, 186 (Tex.Crim.App.1993); Russell v. State, 665 S.W.2d 771, 776 (Tex.Crim.App.1983) (en banc).
To support a conviction for murder, the State had to prove that appellant (1) intentionally or knowingly caused the death of James Playnonero by shooting him with a firearm or (2) intended to cause serious bodily injury and committed an act clearly dangerous to human life that caused the death of James Playnonero by shooting him with a firearm. See TEX.PENAL CODE ANN. § 19.02(b) (Vernon 2003); Sanders, 119 S.W.3d at 820. The State failed to meet this burden.
The evidence produced at trial establishes that someone attacked and killed Playnonero with a firearm. Use of a firearm to cause death establishes that the perpetrator acted with intent to commit murder. See Medina v. State, 7 S.W.3d 633, 637 (Tex.Crim.App.1999); Womble v. State, 618 S.W.2d 59, 64 (Tex.Crim.App.1981). The deficiency in the State's evidence is that it does not establish that appellant was the person who used a firearm to kill Playnonero. As the court of criminal appeals stated in Jones v. State:
The main fact to be proved was that the appellant fired the bullet which killed the deceased into the deceased's forehead. None of the evidence connected with the murder directly demonstrates the main fact. The fingerprints that were "lifted" from the cold Schlitz beer can proved that the appellant handled the beer can sometime during the morning of the murder, but prior to the time when the police arrived. They did not prove that the appellant fired the bullet which killed the deceased.
Jones v. State, 568 S.W.2d 847, 859 (Tex.Crim.App.1978) (en banc). Similarly, in this case, the fingerprints do not prove that appellant fired the weapon that was used to kill Playnonero.
*258 The bloody fingerprints prove that appellant was with the victim after the shooting; however, they are not evidence that appellant was with the victim before the shooting, and an inference to that effect can be reached only by first assuming that appellant was the perpetrator of the murder and then working backwards. The evidence does not prove that appellant had an opportunity to kill the victim. Instead, it proves that appellant was present at the crime scene after the murder, but mere presence is not enough to prove guilt. See Solomon v. State, 49 S.W.3d 356, 361 (Tex.Crim.App.2001); Medina, 7 S.W.3d at 641; Miles v. State, 918 S.W.2d 511, 515 (Tex.Crim.App.1996). Failing to notify authorities of a crime is also not enough. See Medina, 7 S.W.3d at 641.
Although courts have upheld murder convictions based solely on circumstantial evidence, such cases have often involved proof of motive in addition to other incriminating circumstances. See Ates v. State, 21 S.W.3d 384, 390 (Tex.App.-Tyler 2000, no pet.) (holding that proof of motive could be inferred from absence of victim's purse and victim's refusal of defendant's sexual advances); Reeves v. State, 969 S.W.2d 471, 479 (Tex.App.-Waco 1998, pet. ref'd) (holding that defendant had motive because victim did not love him anymore and did not want to be around him and defendant was jealous of victim's other intimate relationships). Although motive is not an element of murder, when identity is called into question, as it is here, proof of motive might be the glue that holds the entire case together. See Guevara v. State, 152 S.W.3d 45, 50 (Tex.Crim.App.2004) ("Motive is a significant circumstance indicating guilt."); King v. State, 29 S.W.3d 556, 565 (Tex.Crim.App.2000) (noting proof of motive along with other incriminating evidence, including DNA evidence and a letter admitting involvement in the murder). At trial, the State produced no evidence that appellant was connected to the victim in any way. In fact, the testimony from the State's witnesses indicated that the police had investigated the relationship between appellant and Playnonero and uncovered no connection whatsoever. A detective who investigated the murder opined at trial that because the victim was involved in the illegal drug trade, the murder could be drug-related. Such strained speculation is far too weak and attenuated a connection to prove a motive sufficient to establish beyond a reasonable doubt appellant's identity as the murderer.
The State has produced no precedent to establish that the evidence in this case is sufficient to prove appellant committed the murder, and we are unaware of any case upholding a conviction based on similar evidence. Accordingly, we reverse the conviction and order a judgment of acquittal.
