Chapter 952 - Penal Code: Offenses
Section 53a-59. - Assault in the first degree: Class B felony: Nonsuspendable sentences.

(a) A person is guilty of assault in the first degree when: (1) With intent to cause serious physical injury to another person, he causes such injury to such person or to a third person by means of a deadly weapon or a dangerous instrument; or (2) with intent to disfigure another person seriously and permanently, or to destroy, amputate or disable permanently a member or organ of his body, he causes such injury to such person or to a third person; or (3) under circumstances evincing an extreme indifference to human life he recklessly engages in conduct which creates a risk of death to another person, and thereby causes serious physical injury to another person; or (4) with intent to cause serious physical injury to another person and while aided by two or more other persons actually present, he causes such injury to such person or to a third person; or (5) with intent to cause physical injury to another person, he causes such injury to such person or to a third person by means of the discharge of a firearm.

(b) Assault in the first degree is a class B felony provided (1) any person found guilty under subdivision (1) of subsection (a) shall be sentenced to a term of imprisonment of which five years of the sentence imposed may not be suspended or reduced by the court and (2) any person found guilty under subsection (a) shall be sentenced to a term of imprisonment of which ten years of the sentence imposed may not be suspended or reduced by the court if the victim of the offense is a person under ten years of age or if the victim of the offense is a witness, as defined in section 53a-146, and the actor knew the victim was a witness.

History: P.A. 80-442 added proviso in Subsec. (b) requiring at least 5 years' imprisonment for person found guilty under Subsec. (a)(1), effective July 1, 1981; P.A. 92-87 added Subsec. (a)(4) re causing serious physical injury to another person while aided by two or more other persons actually present; July Sp. Sess. P.A. 94-2 added Subsec. (a)(5) re causing physical injury to another person or to a third person by means of the discharge of a firearm; P.A. 95-142 added Subsec. (b)(2) requiring the defendant to be sentenced to a term of imprisonment of which 10 years of the sentence imposed may not be suspended or reduced by the court if the victim is under 10 years of age; P.A. 99-240 amended Subsec. (b)(2) to make the nonsuspendable sentence applicable if the victim of the offense is a witness, as defined in Sec. 53a-146, and the actor knew the victim was a witness.

Assault statute provides for intent to be transferred and does not require that defendant be aware of the presence of unintended victim. 84 CA 263. In challenge of evidence as being insufficient to prove element that appellant was “aided by two or more other persons actually present”, where appellant and another defendant assaulted the driver of a jeep while a third defendant assaulted the passenger of a jeep and a fourth defendant kept lookout, it was reasonable for the jury to conclude that the lookout aided in the assault by following the jeep, blocking the jeep from exiting an alleyway and acting as a lookout, and it was reasonable for the jury to conclude that appellant and other two defendants had aided each other by attacking from both sides of the jeep so that neither victim could assist the other or run for help. 111 CA 184. Re accessory liability under section, defendant only needs to have the intent to cause serious physical injury, not the intent to do so with a dangerous instrument; jury could have reasonably inferred that defendant intended to aid another to inflict serious physical injury on victim and that principal used a dangerous instrument. 136 CA 568; judgment reversed on eyewitness identification, see 314 C. 131. Convictions for assault in the first degree in violation of this section and risk of injury to a child in violation of Sec. 53-21, revised to 1997, are separate and distinct offenses for purposes of double jeopardy. 145 CA 374.

Subdiv. (1): Under appropriate circumstances, defendant can simultaneously intend to cause death of, and serious physical injury to, same person; judgment of Appellate Court in 39 CA 18 reversed. Id., 748. Cited. 239 C. 481; 240 C. 395; 241 C. 665; Id., 802; 242 C. 143; Id., 485; Id., 723; Id., 745. Subdiv. (3): Criminal conduct can arise by an omission to act when there is a legal duty to do so and defendant who had established a familial relationship with victim's mother and her children, had assumed responsibility for the welfare of the children and had taken care of the children as though he were their father, had a legal duty to protect victim from abuse and breach of that duty exposed defendant to criminal liability. 245 C. 209. Cited. 247 C. 662. Defendant was not without fair warning and his due process rights were not denied by court's holding construing a common law duty to act under section; evidence that child abuse victim had sustained obvious injuries was sufficient to support defendant's conviction based on his failure to act; re double jeopardy claim, defendant failed to meet his burden of proving that his conviction with regard to different injuries arose out of the same act; this section and Sec. 53-21 do not stand in relationship to each other as greater and lesser included offenses and are not the same offense for double jeopardy purposes. 260 C. 93. Defendant who was not perpetrator of physical assaults on child and who was neither a parent nor a legal guardian could not be criminally liable for assault in the first degree in violation of Subdiv. (3); accordingly, defendant's conviction of two counts of that crime were reversed and case remanded for resentencing on remaining charge of risk of injury to a child. 274 C. 727. Sec. 53a-61(a)(2) is lesser included offense of Subdiv. (3), and court's refusal to grant related jury instruction constituted harmful error. 289 C. 742. Subdiv. (1): A fist or other body part is not a dangerous instrument. 307 C. 115. Convictions under Subdivs. (1) and (3) are not legally inconsistent because a person may intend to seriously injure a person within the meaning of Subdiv. (1) while simultaneously recklessly creating a risk of that person's death within the meaning of Subdiv. (3). 316 C. 651. Subsection's use of “serious disfigurement” evidences intent to require consideration of factors such as permanence, location, size, general appearance and visibility to others; serious disfigurement does not have to be permanent or in a location that is visible to others. 332 C. 472. Evidence insufficient to find serious disfigurement where regardless if evaluated at the time of injury or of trial, victim had two lacerations on her forearm caused by a knife that left a permanent scar of one and one-half inches which is unremarkable in appearance and does not substantially detract from her appearance. Id. Where court reversed conviction of assault in the first degree for insufficient evidence, court declined to modify the judgment to reflect the highest lesser included offense that requires only physical injury, assault in the second degree, and remanded case for acquittal and vacating of sentence for said charge. Id. Because Subdiv. (1) does not indicate unit of prosecution intended by legislature, and absent clear legislative intent to impose multiple punishments for violations of same criminal statute arising out of single transaction or occurrence, unit of prosecution must be resolved in favor of rule of lenity to resolve any doubt against turning a single transaction into multiple offenses. 336 C. 219. Subdiv. (1): It is possible to commit the crime of home invasion without committing the crime of attempt to commit assault in the first degree, therefore home invasion in violation of Sec. 53a-100aa(a)(2) and attempt to commit assault in the first degree in violation of Subdiv. and Sec. 53a-49 are not the same offense for purposes of double jeopardy. 343 C. 470.

Offenses described in Subdivs. (1) and (4) are two separate offenses for purposes of double jeopardy. 53 CA 581. To secure conviction for assault in the first degree under Subdiv. (1), state must establish beyond a reasonable doubt that defendant intended to cause serious physical injury to another person, did, in fact, cause serious physical injury to that person and caused that injury by means of a dangerous instrument. 70 CA 232. There was sufficient evidence from which jury reasonably could have found victim had suffered serious and permanent disfigurement and that defendant intended to cause such serious and permanent disfigurement where defendant butted victim's face with his head, bit her face, struck her on the head with a hairdryer, kicked her and attempted to choke her, resulting in scars to victim's face. 74 CA 633. Defendant's actions in shaking infant with such violence as to cause injuries consistent with “shaken baby syndrome” was a gross deviation from the standard of conduct a reasonable person would observe and evinced extreme indifference to human life. Id., 736. Subdiv. (2): Fact that the wounds actually inflicted by defendant were relatively minor does not mean that there was insufficient evidence to find that he intended to inflict serious injury. 78 CA 646. Subdiv. (1): Evidence that defendant arrived at crime scene and fired several shots at bedroom where he believed wife was staying was sufficient for jury to conclude that defendant committed attempt to commit assault in the first degree which requires proof of intentional conduct constituting a substantial step toward intentionally causing victim serious physical injury by means of a dangerous instrument or deadly weapon. 99 CA 203. Subdiv. (5): Court's instructions to jury improperly included additional element of intent to use firearm but did not prejudice defendant because inclusion of the additional element was to the state's, and not to defendant's, detriment. 107 CA 517. The jury reasonably could have concluded that scars constituted serious physical injury because they negatively affected the appearance of skin on face and abdomen. 118 CA 831. Mandatory nonsuspendable 5 year minimum term of imprisonment for violation of Subdiv. (1) does not violate constitutional due process or equal protection rights. 130 CA 632. Scarring does not have to be on a victim's face, it can be on far less observable parts of the body to support a finding of serious disfigurement; victim suffered serious disfigurement when scar was permanent, easily seen two and one-half years after the injury, and was located on the lower part of arm. 172 CA 668; judgment reversed in part, see 332 C. 472. Subdiv. (3): Conviction under Subdiv. and Sec. 53a-55(a)(3) constituted double jeopardy violation because there was no conceivable circumstance in which defendant could have caused victim's death without also having caused victim “serious physical injury” as defined in Sec. 53a-3(4). 187 CA 725. Attempted murder under Sec. 53a-49(a) and assault in the first degree under this section are not the same offense of for purposes of double jeopardy. 204 CA 207.
