OPINION
This case comes before us on the appeal of the defendant, Donna Dellatore, from a judgment of conviction entered in the Superior Court in which a jury found her guilty of second-degree murder. The trial justice denied the defendant’s motion for a new trial, sentenced her to fifty years imprisonment (with thirty years to serve and twenty years suspended with probation), and ordered her to attend counseling upon her release. This appeal followed. We affirm the judgment of the Superior Court. The facts insofar as pertinent to this appeal are as follows.
On February 12, 1994, Donna Dellatore (defendant) began complaining of pain to Armando Mejia (Mejia), her partner, with whom she shared an apartment at 144 Central Street in Central Falls. The pain continued into the following day. The defendant refused Mejia’s offers to take her to the hospital and instead sent him to the store to purchase medicine for menstrual cramps and sanitary napkins. On February 14, Mejia went to work with defendant’s assurances that she would be fine. Concerned about defendant’s condition, Mejia returned home early from work and found defendant in bed. Upon seeing Mejia, defendant stated, “I’m sorry, I’m sorry * * * I didn’t know we were pregnant.” She then told Mejia that she had given birth to a baby while he was at work. Mejia entered the bathroom and found the baby in the toilet. After the baby failed to respond to his touch or display any signs of life, Mejia proceeded to leave the apartment and call the paramedics.
Shortly thereafter, the paramedics arrived at defendant’s apartment. Upon entering the apartment, they found defendant wrapped in a blanket, lying on a mattress on the floor. The paramedics were then led into the bathroom by Mejia. They found the body of a newborn girl in the toilet, partially submerged in water. After checking for vital signs, the infant was declared “DOA” (Dead on Time of Arrival). The defendant was then taken to the hospital by the paramedics. At the hospital, defendant acknowledged that she had given birth to a baby that morning. She also admitted that her stomach had become larger and that she had had no menstrual periods since the previous May. However, because her menstrual cycle had always been irregular (she had often gone several months without menstruating), because she was naturally large in the stomach, and because she was thirty-five-years-old and had never before conceived (despite a previous ten-year marriage), she had not understood that she might be pregnant.
*229 Doctor Elizabeth Laposata (Laposata), the state medical examiner, conducted an autopsy on the baby. Her examination revealed a Y-shaped laceration on the right side of the back of the baby’s skull. Laposata viewed this laceration as evidence of blunt trauma. Underneath that wound was a smaller, “cutting” type of wound, possibly made by a fingernail. An internal examination revealed a depressed skull fracture with an area of hemorrhage underneath the laceration on the right side of the temporal lobe. The examination ' was otherwise unremarkable, indicating a normally developed, full-term baby.
Laposata determined that the baby had not been stillborn. She based this determination on the presence of air in the alveoli of the baby’s lungs, which established that some breathing had taken place, and on the hemorrhaging surrounding the head wound, which indicated “an effective heartbeat,” sufficient to support blood flow throughout the body. The doctor opined that blunt head trauma had been the main cause of the baby’s death.
Based on the fact that the infant had an effective heartbeat, but had never had the opportunity to fully expand her lungs to achieve effective respiration, Laposata concluded that the trauma was sustained very shortly after birth. She said that the absence of any blood in the amniotic fluid and the lack of any injuries to defendant eliminated the possibility that the injuries had occurred before birth because such trauma could not have been suffered by the baby in útero absent the presence of “significant injuries” to the mother.
Laposata rejected the possibility that the infant had suffered the head injury when she fell, unassisted, to the floor or onto the toilet during the birthing process. In order to attain sufficient force to cause the type of injury that the baby suffered, it would have been necessary to not only drop the baby, but also to exert additional energy moving the baby’s body against a blunt surface. This would have required that the baby be “totally expelled from the mother’s body.” Laposata did acknowledge that the injury theoretically could have occurred when the baby had been only partially expelled from the mother’s body, as long as the head had emerged from the birth canal and one had possessed “the geometry and the physical ability” to move the child’s head with sufficient force against a blunt object to effect such trauma. Such a scenario would have required “some very unusual circumstance[s],” such as the mother’s “jumping downstairs with the baby partially protruding from her.”
The defendant was charged with one count of first-degree murder arising out of the death of her newborn infant. During trial, the trial justice granted defendant’s motion for judgment of acquittal on the first-degree murder count, but denied that motion insofar as it sought acquittal on the charges of second-degree murder and manslaughter. The trial justice refused defendant’s request to instruct the jury that for a baby to have been “born alive,” the jury must find that the baby had been fully expelled from her mother’s body and that she had had a separate and independent existence. Such a finding, defendant argued, was necessary to sustain a homicide conviction for the baby’s death.
See State v. Amaro,
“Request # 9: Separate and independent existence means that the injury must have been inflicted when the baby was fully expelled from the mother. In other words, if you are not satisfied beyond a reasonable doubt to this point, you must acquit.
“Request # 10: In order to prove that the baby was born alive, the main evidence is whether the child took a breath.
“Request #11: In order to prove that the baby was born alive, you may consider as factors whether there was air in the lungs, whether the baby breathed, *230 did the baby cry, was the body moving, were there any problems with the birthing process.
“Request # 12: In order to prove a separate and independent existence, you must find that the baby had breathed in order to attain separate respiration and circulation from the mother.”
The trial justice instead instructed the jury as follows:
“First of all, there cannot be a murder unless there is a live victim. So, the State has the obligation of proving to you through the evidence that Baby Del-latore at the relevant times was alive, and that the baby had the capacity and capability of living separate and apart from its mother upon being delivered out of the womb, and that the baby, as I say, lived separate and apart without artificial means, such as an incubator or special extraordinary drugs or something of that nature being administered to it. In other words, it was a basically normal, healthy baby, and that if all other things had been appropriate it could have lived. That is what being born alive means.
“Obviously, if you conclude, based upon the evidence that the baby was born dead, it was stillborn, well, then, there cannot be a second degree murder. The ancient common law has examples of someone going through a window in the middle of the night bent upon killing someone, they find out later that the person, the intended victim had actually died two days earlier. While the person may have stabbed something, it was not stabbing a living human being, so there was no murder. Similarly, in this case, the baby must have been born alive; that is one element the State must show.”
On appeal, defendant contends that the trial justice erred in refusing defendant’s request, and, in so doing, committed reversible error.
A trial justice “shall instruct the jury in the law relating to the action.” G.L.1956 § 8-2-38;
see State v. Arpin,
The
Amaro
test requires that a victim be “born alive” in order to sustain a criminal conviction for homicide.
See Amaro,
Moreover, “a trial justice need only instruct a jury regarding those rules of law that must be applied to the issues raised at the trial.”
State v. Medeiros,
The second part of the Amaro test requires that “independent vitality” be shown. This part of the test similarly was addressed by the trial justice’s instructions. The trial justice said in his instructions that the baby had to have “the capacity and capability of living separate and apart from its mother,” and that it must in fact have “lived separate and apart without artificial means.” The trial justice’s reference to a “capacity” and a “capability” of living separate and apart from the mother did not change or muddle the meaning of his instruction; he stressed that the child had to have “lived separate and apart without artificial means.” His directive was clear. Any reasonably intelligent juror would have had no difficulty in discerning that a physically independent existence depended upon the sufficient development of the baby’s own circulatory and respiratory systems.
The defendant also argues that the court erred in refusing to give defendant’s requested mistake-of-fact instruction. In appropriate circumstances, this Court does recognize the mistake-of-fact defense.
See State v. Tevay,
Finally, defendant argues that the trial justice erred in restricting the portions of the medical examiner’s testimony read back to the jury. It is well established that the decision to have testimony read back to the jury during deliberations is within the sound discretion of the trial court.
See State v. Dame,
For the reasons stated, the defendant’s appeal is denied and the judgment of conviction is affirmed. The papers in the case may be remanded to the Superior Court.
Notes
. Laposata explained that the scale measured force by looking at the displacement in the head caused by the injury. She explained that there was a continuum of injury that spanned from the least amount of displacement (that is, a bruise) to the greatest amount of displacement (that is, an open skull fracture with bone fragmentation).
