*73 OPINION OF THE COURT BY
Defendant Tamara Sue Kreps (Kreps) appeals from her conviction of Negligent Homicide in the First Degree, Hawaii Revised Statutes (HRS) § 707-703(1) (1976). Kreps raises the following issues on appeal: (1) the trial court erred in dеnying her Motion for Judgment of Acquittal as to the charge of Negligent Homicide in the First Degree; and (2) the trial court erred in denying her motion to suppress her pre-trial inculpatory statements. We find no error and affirm.
On July 20, 1980, betwеen 5:30 a.m. and 6:00 a.m., Kreps was driving an automobile in a Diamond Head (easterly) direction on Kuhio Avenue when she struck and killed a pedestrian, Audrey Norris. Kreps had spent the previous evening at a nightclub with her roommatе, but was driving back to her apartment alone. As she entered Kuhio Avenue from Kalakaua Avenue, she saw a pedestrian crossing the street. Kreps “downshifted” from third to second gear but did not brake, thinking that she had passеd the pedestrian. The next thing Kreps saw was something crashing into the windshield. She stopped and saw a person lying in the street behind the car. She then reversed the car to where the body was lying.
Police arrested Kreps at the scene of the accident for driving without a license. She was taken to the Honolulu Police Station where, at 7:30 a.m., a breathalyzer test was administered which indicated Kreps’ blood alcohol level at 0.12 percent.

Kreps was in the process of being discharged when Officer Larry Walter (Walter) introduced himself, indicated that he wished to talk about the accident and asked her to accompany him to his оffice. At his office, Walter produced a form, HPD Form 81, bearing the constitutional rights warnings required by
Miranda
v.
Arizona,
Walter testified that although Kreps appeared emotionally upset throughout the interview and cried from time to time, she did not appear to be intoxicated, appeared “in control,” and responded to all of his questions.
On December 23, 1980, the Oahu Grand Jury indicted Kreps for the offenses of Negligent Homicide in the First Degree, HRS § 707-703 (1976), and Driving Without a License, HRS § 286-102 (1976, as amended). On March 2, 1981, Kreps filed a motion to suppress her statements along with a motion to dismiss the grand jury indictment. Both motions were denied in an order filed on April 21, 1981.
A jury trial was commenced on May 19, 1981. At the close of the State’s case, Kreps moved for a judgment of acquittal as to both counts. The court orally denied the motion.
After a recess for lunch, the State made a motion to reopen the case. Upon the motion being granted, the State presented evidence that Audrey Norris died as a result of the accident.
At the close of the State’s evidence, the court again denied Kreps’ motion for judgment of acquittal. Kreps presented evidence and, at the end of trial, made a third motion for judgment of acquittal, which was also denied.
On May 22,1981, the jury found Kreps guilty as charged on both counts. On May 28, 1981, Kreps filed a motion for judgment of acquittal. After hearing, the court granted the motion as to the license count but denied it as to the negligent homicide count.
On July 27, 1981, the court sentenced Kreps to five years probation. This timely appeal followed.
*75 I.
Kreps contends that the trial court erred in denying her motion for judgment of acquittal after the State had originally rested. She argues that at that time, the State had failed to present a prima facie case because it did not prove that Audrey Norris had died as the result of the accidеnt. Since it was necessary for the court to allow the State to reopen its case in order to introduce evidence of the cause of death, the motion for judgment of acquittal should have been granted. Kreps does not raise as error the trial court’s granting of the State’s motion to reopen.
We note first that this court has adopted the majority rule that a defendant who presents evidence after а denial of his or her motion for judgment of acquittal at the close of the State’s case thereby waives any error in that ruling by the trial court.
State
v.
Emmsley,
II.
Kreps also asserts that the trial court erred in denying her motion to suppress her statements. She contends that there was no knowing and intelligent waiver of her rights and her statement was not voluntary because at the time of the interrogation, she was emotionally upset, confused, frightened and “somewhat inebriated.”
A defendant’s statement may not be received in evidence until the prosecutor has shown that the defendant was warned of his rights pursuant to
Miranda
v.
Arizona, supra. See also State
v.
Santiago,
In addition to the necessary waiver the court must аlso find that such a statement was voluntarily made.
State
v.
Pahio,
The general rule is that, in the absence of insanity or mental depletion, neither the voluntary character nor the admissibility of a confession is affected by the mental instability of the person making it. State v. Foster, supra.
*78 That condition is one for the consideration of the jury in determining the weight or effect to be given to the confession or statement.... “Evidence tending to establish that a confessor was ill or in a hysterical condition, and therefore not in full possession of his faculties at the time he confessed his guilt, does not affect the admissibility of the confession, but bears on the weight and effect to be given the confession. * * * ” [Citations omitted.]

Furthermore, еvidence that a defendant was intoxicated at the time he confessed or made an inculpatory statement will not, without more, prevent the admissibility of the confession or statement.
State
v.
Curry,
In the instant case, there is conflicting testimony regarding Kreps’ emotional and physical condition at the time of the inculpatory statement. The trial court, after weighing the evidence and the credibility of the witnesses, determined that the statements were admissible. There is ample evidence to support the court’s ruling. As we have previously noted, Walter testified that although Kreps was a bit disheveled, she had no problems walking or standing nor did he detect any alcohol on her breath prior to and during the interview. He further testified that although she appeared emotionally upset and had cried from time to time, Kreps did not havе any trouble speaking, appeared “in control” and responded to all of his questions. The fact that Kreps was upset, confused, frightened and possibly inebriated would not per se require the court to find that she had not made a knowing and intelligent waiver or that her statements were not made voluntarily. State v. Foster, supra; State v. Curry, supra; State v. Baker, supra; State v. Smith, supra. Defendant has failed to demonstrate any abuse of discretion by the trial court in the denial of her motion and *79 we find no error.
Affirmed.
Notes
Kreps did not raise in her motion the failure of the State to prove the cause of death. Kreps.specifically argued as the basis for her motion that the Stаte had failed to prove beyond a reasonable doubt that defendant’s actions were negligent and that she possessed the state of mind requisite to penal liability for her actions. An appellate court will not consider matters which have not been raised before the trial court except where the defendant’s substantial rights may have been affected because of plain error.
Eli
v.
State.
Additionally, some authorities hold that the grounds for a motion for judgment of acquittal need not be stated with specificity unless so requested. 8A Moore’s Federal Practice ¶ 29.03[1] (2d ed. 1982); 2 Wright & Miller, Federal Practice & Procedure:
Criminal
§466 (1982). However, once the defendant has chosen to spеcify the grounds upon which he intends to base his motion for judgment of acquittal, he may not later contend that there were other areas upon which his motion for judgment of acquittal

would lie.

Price,
Concerning
State
v.
Green, supra,
we stated in
State
v.
Kalani,
Although we are bound by the holding in Green, as followed in Maluia and Liuafi, we are constrained to point out that Justice Levinson’s statement in Green, that the standard of review is “abuse of discretion,” is really too broad, although it is possible to read Green to mean that thе discretion of the trial judge is limited to the determination of credibility. We recently held in State v. Tuua, 3 Haw. App. [287],649 P.2d 1188 (1982)[,] that the standard of review involving the admission of out-of-court identification in criminal cases is the clearly erroneous rule, citing State v. Patterson,58 Haw. 462 ,571 P.2d 745 (1977). We think the same rule should apply to appellate review of the trial court’s admission of confessions. Cf. United States v. Benedict,647 F.2d 928 (9th Cir. 1980); United States v. Dufur,648 F.2d 512 (9th Cir. 1980); United States v. Gorel,622 F.2d 100 (5th Cir. 1980); United States v. Schmidt,573 F.2d 1057 (9th Cir. 1978). Were we to apply the clearly erroneous rule in the case at bar, the result would be the same.
