OPINION ON APPELLANT’S PETITION FOR DISCRETIONARY REVIEW
PER CURIAM.A jury convicted appellant of murder and assessed his punishment at seventy-five years imprisonment. The conviction was affirmed. Saunders v. State, 780 S.W.2d 471 (Tex.App.—Corpus Christi 1989). We granted appellant’s petition to determine whether a requested jury instruction for the offense of criminally negligent homicide should have been given.
Two months after the seventeen year-old appellant began sharing an apartment with his girlfriend, Reba Ann McFadden, McFadden’s five month-old child Darrell was found dead in his crib. Fifteen days earlier a witness saw appellant cursing the crying baby, and telling the child to shut up while squeezing the back of his neck. A medical expert believed one cause of Darrell’s death was an epidural hemorrhage stemming from fractures in the skull which probably were caused by squeezing the child’s head with a hand on more than one occasion. The squeezing would not have required much pressure to cause the fracture, and no noise would accompany the fracture.
*391Other evidence indicated that at various times during the fifteen days prior to his death, Darrell appeared to have facial bruises and scratches. There were abrasions to the child’s nose, ears, and chin, which were apparently caused by pinching. A hole at least one inch in diameter in the back of the head was an ulceration of a bruise or laceration which probably was caused by an instrument, not a hand. Bruises along the spine could have resulted from a fall, but more likely stemmed from moderately hard slaps or blows to the back. A healing injury to the liver was probably caused by a blow incurred about three days earlier. The child also suffered a subdural hemorrhage which contributed to his death. The subdural hemorrhage was caused by a shaking of the child or a blow to his head, occurring sometime about two weeks before death.
At trial appellant’s counsel requested an instruction on criminally negligent homicide, dictating a proposed charge defining criminal negligence and applying that definition to allow conviction if the jury believed appellant with criminal negligence caused Darrell’s death by squeezing his head. This request was denied without further discussion. The trial court did submit an instruction on the lesser offense of involuntary manslaughter.
The Court of Appeals noted that a charge on a lesser included offense must be submitted if two requirements are met: first, the lesser included offense must be included within the proof necessary to establish the offense charged; and second, there must be some evidence in the record that if the defendant is guilty, he is guilty of only the lesser offense, citing Royster v. State, 622 S.W.2d 442 (Tex.Cr.App.1981) (opinion on rehearing). The court also noted that criminally negligent homicide is the failure of the actor to perceive the risk created by his conduct, and a charge is not required unless the evidence shows that the actor was unaware of the risk his conduct created.
The Court of Appeals examined the record and stated that it found no evidence from any source indicating that if appellant was guilty of causing the victim’s death by squeezing his head, appellant was guilty only of criminally negligent homicide. The court concluded that the trial court did not err in overruling appellant’s request for the jury charge on the lesser offense.
In his petition appellant complains that the Court of Appeals ignored evidence that appellant failed to perceive that the baby was in danger of dying, and that appellant may well not have perceived the nature and extent of the risk involved in squeezing the baby’s head. Appellant refers to Thomas v. State, 699 S.W.2d 845 (Tex.Cr.App.1985), and argues that if the evidence raises two inferences regarding the accused's awareness of the risk, the jury should be instructed on both.
Criminally negligent homicide is a lesser included offense of murder, Hunter v. State, 647 S.W.2d 657 (Tex.Cr.App.1983), so the only question presented in this case is whether this record contains evidence that appellant is “guilty only” of criminally negligent homicide.
It is well established that if evidence from any source raises the issue of a lesser included offense, a charge on that offense must be included in the court's charge. Ojeda v. State, 712 S.W.2d 742 (Tex.Cr.App.1986), citing Bell v. State, 693 S.W.2d 434 (Tex.Cr.App.1985), and Moore v. State, 574 S.W.2d 122 (Tex.Cr.App.1978). The credibility of the evidence and whether it conflicts with other evidence must not be considered in deciding whether the charge on the lesser offense should be given. Lugo v. State, 667 S.W.2d 144 (Tex.Cr.App.1984); Thomas, supra at 849, citing Moore, supra. Thus, regardless of the strength or weakness of the evidence, if any evidence raises the issue that the defendant was guilty only of the lesser offense, then the charge must be given.
There are two ways in which the evidence may indicate that a defendant is guilty only of the lesser offense. First, there may be evidence which refutes or negates other evidence establishing the greater offense. For instance, if a defendant is charged with aggravated robbery and evidence is presented which indicates *392the defendant may not have used a deadly weapon, then a charge on the lesser offense of robbery would be required. If, however, the defendant simply denies commission of the offense, see e.g., McKinney v. State, 627 S.W.2d 731 (Tex.Cr.App.1982); McCardell v. State, 557 S.W.2d 289 (Tex.Cr.App.1977), or there is no evidence specifically raising an issue regarding use of the weapon, see e.g. Denison v. State, 651 S.W.2d 754 (Tex.Cr.App.1983), and Thomas v. State, 543 S.W.2d 645 (Tex.Cr.App.1976), then the charge on the lesser offense would not be required.
Second, a defendant may be shown to be guilty only of the lesser offense if the evidence presented is subject to different interpretations. In Thomas, 699 S.W.2d at 851, this Court held that if the evidence raises two inferences regarding the defendant’s awareness of the risk, then the jury should be instructed on both inferences, citing Schoelman v. State, 644 S.W.2d 727 (Tex.Cr.App.1983).
For instance, in Lugo the defendant was charged with murder. He claimed on appeal that the jury should have been charged on involuntary manslaughter. The evidence showed that the defendant pointed a loaded rifle at his wife to persuade her to relinquish the car keys. This evidence could have been interpreted to show that the defendant intentionally pointed the riñe at the wife knowing it was loaded and then intentionally shot her, or it could have been interpreted to show that the defendant consciously disregarded a substantial risk. This Court held that the evidence showed that the defendant could have been guilty only of the lesser offense and the charge should have been given. See also Bell, supra, and Aguilar v. State, 682 S.W.2d 556 (Tex.Cr.App.1985). But cf. Godsey v. State, 719 S.W.2d 578 (Tex.Cr.App.1986) (The evidence manifested only an intent to kill the officer and did not show mere threat with a gun so that a charge on aggravated assault or reckless conduct was required.)
In the instant case, appellant’s mental state was shown circumstantially. No direct evidence was presented regarding appellant's intent to kill or injure, his knowledge that death could result, or his awareness that a risk of death existed. The evidence simply showed that appellant had squeezed the back of the baby’s head fifteen days before the child’s death, which was likely caused by a similar squeeze.
Although other circumstances existed from which a jury could conclude appellant knew his treatment of Darrell might kill him, a jury could also conclude based on the same evidence that appellant may not have known his actions could kill the baby, even though he ought to have been aware of this risk. Under the latter interpretation, appellant could have been guilty only of the lesser offense of criminally negligent homicide. Because this evidence was subject to different interpretations and raised the issue that appellant was criminally negligent in squeezing the child’s head, appellant’s requested instruction on criminally negligent homicide should have been given. The Court of Appeals erred in holding criminal negligence was not raised by the evidence.
We therefore reverse the judgment of the Court of Appeals and remand the cause to that court to conduct a harm analysis under Almanza v. State, 686 S.W.2d 157 (Tex.Cr.App.1984). See Arline v. State, 721 S.W.2d 348 (Tex.Cr.App.1986).
