APPEAL from the Circuit Court of St. Clair County; the Hon.
JOHN J. HOBAN, Judge, presiding.
MR. JUSTICE HARRISON DELIVERED THE OPINION OF THE COURT:
The defendant, James Drummond, appeals his conviction for murder (Ill. Rev. Stat. 1977, ch. 38, par. 9-1(a)(1)) before a jury of his peers in the circuit court of St. Clair County on May 23, 1979. The central issue at trial and on appeal involves the affirmative defense of insanity. Drummond maintains that it was error for the court below to refuse his tendered instructions regarding insanity based upon pertinent evidence presented at trial and that it was erroneous to deny the admission in evidence of lay opinion testimony concerning the defendant's sanity prior to the shooting. It is also argued that a possible conflict of interest on the part of defense counsel was alluded to in the course of testimony, that the defense counsel precluded its explication by objection, and that the cause should be remanded to fully explore the alleged conflict. We affirm the court below.
The regrettable events which led up to the tragic violence involved in this case began on the morning of July 18, 1978. The defendant, employed as the produce manager of a Tri-City Grocery Store in East St. Louis, Illinois, was the third-ranking management employee in the store and had been associated with the company for some eight years. At approximately 10 a.m. Drummond was informed that he was being dismissed because he had violated a company rule against using a store telephone for personal toll calls. The defendant alleged that the cited reason was a pretext to cover the management's genuine motivation, that of replacing him with an employee from another of the company's stores which was scheduled to be closed shortly. Several discussions followed between Drummond and management supervisors within the store, and later, two higher company officials came to the store to discuss the firing. Prior to their arrival the defendant had left the store and returned, having imbibed both alcohol and marijuana in the interim. After all his attempts to prevail upon them failed, the defendant drove away in a highly distraught condition. He stopped the car only 50 yards from the store, took a pistol from the trunk, and then made his way back to the front of the building on foot. He met the victim, Vance Morgan, and another store official, Rex Cress, exiting through the store's automatic doors. Holding his gun on both, the defendant followed the two as they backed into the front lobby where Morgan suggested they discuss the matter further. The assailant replied, saying, "You took it, you are taking the food out of my boy's mouth, and it is too late for talk," and shot Morgan to death as he crouched in the end of one of the check lanes. Then Drummond attempted to find and shoot Cress who had fled out the rear of the store. Unable to find him within the store, the defendant left, discarded the gun, and drove to his home where police arrested him minutes after his arrival.
The only issue in contention at trial was the defendant's mental state during the commission of the crime. In essence the defense attempted to establish that due to economic difficulties and serious marital problems in the weeks prior, the defendant was suffering from what a psychiatrist testified was reactive neurotic depression, a mental disease, which it argued substantially impaired his ability to conform his conduct to the requirements of law. (See Ill. Rev. Stat. 1977, ch. 38, par. 6-2(a).) In addition to expert testimony Drummond attempted to show mental disease through the testimony of other store employees who witnessed the incident or who had spoken to the defendant that morning. We will review both strains of this evidence in greater detail below. During an instruction conference held after the defense rested, the court denied defense counsel's tendered instructions defining and placing in issue the defense of insanity (IPI Criminal Nos. 24.01 and 25.01). Subsequently, the jury found defendant guilty of murder, and he was sentenced by the court to a 25-year term of imprisonment.
• 1 First, turning to the issue of the refused jury instructions, it is the position of the appellant that sufficient evidence calling into question the sanity of the defendant was entered at trial to support the submission of the issue to the jury. The exculpating excuse of insanity is an affirmative defense. (People v. Jackson (1978), 57 Ill. App.3d 809, 814, 373 N.E.2d 583; Ill. Rev. Stat. 1977, ch. 38, par. 6-2.) According to the statutory definition of its operative effect, an affirmative defense must be raised by the defendant through the presentation of "some evidence," unless prosecutorial evidence has first called it into issue. (Ill. Rev. Stat. 1977, ch. 38, par. 3-2.) Although there is a conflict among the authorities regarding the threshold quantum of evidence required to warrant instructing the jury as to affirmative defenses in general (People v. Creach (1979), 69 Ill. App.3d 874, 896, 904, 387 N.E.2d 762; see, e.g., People v. White (1979), 78 Ill. App.3d 979, 981, 397 N.E.2d 1246 (necessity); People v. Adcock (1975), 29 Ill. App.3d 917, 919, 331 N.E.2d 573 (compulsion)), it is the settled law of this State that the defense of insanity must be supported by evidence which raises a reasonable doubt concerning the accused's sanity. (People v. Redmond (1974), 59 Ill.2d 328, 338, 320 N.E.2d 321; People v. Smothers (1973), 55 Ill.2d 172, 174-75, 302 N.E.2d 324.) We are bound by the same measure of proof in reviewing the refusal of jury instructions on this issue. People v. Smothers (1973), 55 Ill.2d 172, 175; People v. Proper (1979), 68 Ill. App.3d 250, 253, 385 N.E.2d 882; People v. Gilley (1976), 40 Ill. App.3d 824, 827, 353 N.E.2d 88.
• 2 By this standard we cannot say that the court below was in error because it denied the instructions involved. To begin with, the testimony of the defendant's single expert witness was highly equivocal. Dr. Peter Heinbecker, a psychiatrist, offered the following in response to a hypothetical question on whether the defendant was suffering from a mental defect or disease at the time of the shooting, the product of which substantially impaired his ability to conform his conduct to the requirements of law:
"A. Well, I feel that to a certain extent, the defendant was not able to control his conduct at that time, and that the depression played a part in it, but I feel the anger at being fired was the more important element in the loss of control, which he displayed by shooting somebody in front of 16 or 20 people.
When I think of substantial in that term, what I am thinking of is if the depression alone were there, would that have resulted in the loss of control, and I don't believe that the depression alone would have been sufficient to result in the loss of control. I feel that the result and anger at being fired was the more substantial part of what happened.
Q. All right. And do you feel that the anger was a product of the mental defect that you found in the defendant?
MR. ENGLISH: He has already answered that question.
THE COURT: I don't believe he has. He may answer.
A. Well, I think that the depression influenced the anger, but I think that the anger was not totally resulted [sic] the depression. I think it was basically, and most importantly a result of his being fired in the manner in which he was fired."
And upon cross-examination:
"Q. Well Doctor, again what mental disease or defect did ...
