Aftеr trial to a jury the defendant was convicted of robbery, use of a firearm in the commission of a felony, and being an habitual criminal. He was sentenced to consecutive terms of imprisonment for 10 years on each count.
The defendant has appealed and has assigned as error (1) failure to admit evidence of other similar crimes committed while the defendant was incarcerated аs proof that defendant was not guilty of the robbery charged, (2) failure to declare a mistrial when the State violated a pretrial order, (3) misconduct of the county attorney in failing to disclose statements made by the defendant’s accomplice, (4) prosecutorial misconduct in failing to disclose the true nature of the plea bargain with a prosecuting witness who was granted immunity, (5) prosecutоrial misconduct in failing to disclose exculpatory evidence, (6) prosecutorial misconduct in vouching for the credibility of a witness for the State, (7) prosecutorial misconduct in using the testimony of a witness who had failed a polygraph examination, and (8) the imposition of consecutive habitual criminal sentences where both crimes arose out of one transaction.
The robbery took рlace at the Burger King Restaurant in Lincoln, Nebraska, on September 17, 1979. The robbery was perpetrated by two black men, one about 6 feet 3 inches tall and the other approximately 5 feet 7 or 8 inches tall. Both men wore homemade masks over their faces. The employees, except the manager, were ordered into a utility room in the building. The taller man brandished a gun while the shorter mаn ordered the restaurant manager to open the cash drawers and took the money.
On September 27, 1979, the defendant and Elizabeth Hippie were stopped by police near 49th and Claire *887 Streets in Lincoln, pat-searched, and taken to police headquarters for questioning concerning the Burger King robbery. After lengthy questioning Hippie gave a statement to police in which she admitted that she, the defendant, and Kevin Ginger had committed the robbery. According to Hippie, on the evening of September 16, 1979, she, the defendant, and Ginger drove around the north part of Lincoln in her automobile while the defendant and Ginger discussed robbing the Burger King Restaurant. Ginger showed Hippie a homemade mask made out of a T-shirt that he intended to wear. Hippie saw the defendant remove a pistol frоm his pocket, place a bullet in the chamber, and put the pistol back in his pocket.
Late that evening the car was parked at 25th and Dudley Streets, and the defendant and Ginger left the automobile. Hippie waited in the car at 25th and Dudley for an estimated 1 to V/2 hours. When the defendant and Ginger returned to the car the defendant directed her to open the trunk, and the defendant and Ginger climbed into the trunk. She then drove to Ginger’s apartment. When they arrived at the apartment she opened the trunk, and the defendant and Ginger got out. Hippie stated that there was money strewn around the trunk. The three of them picked up all the money and went into Kevin Ginger’s apartment where the defendant counted the money and divided it. Hippie received about $500. Hippie and the defendant spent the remainder of the night at Ginger’s apartment, and left early the next morning.
Approximately five Burger King employees, including the manager, were in the building at the time of the robbery. They testified, in substance, that shortly after closing, when one of the employees was taking out the trash, two men accosted him in the alley behind the restaurant and forced him back into the building. The men ordered the employees, except thе manager, into a utility room. The taller robber grabbed the manager and demanded to know where the money was. The *888 shorter man then took over the task of getting the money, going up to the front of the restaurant with the manager, while the tall man stood at the back, holding the gun and making threatening comments. After the shorter man had obtained the money, both men left and the police were called. The testimony of the employees corroborated Hippie’s testimony as to what the defendant had told her about what had happened inside the restaurant during the robbery.
Hippie testified that while the police were following her automobile on the night of the arrest, the defendant handed a .38-caliber automatic pistol to her and asked her to hide it. Hippie hid the gun in the front of her jeans, and it was not found during the pat-search. Later, while she was being questioned at the police station, she requested permission to use the bathroom, and hid the gun in a wastebasket. Sometime later she advised her attorney about the gun. The attorney notified the police who then retrieved the gun.
In exchange for her testimony as a witness for the State, Hippie was granted immunity from prosecution “from anything that arose out of the transaction that took place involving the Burger King robbery or incidents related thereto.” There was some testimony at the trial that she would not be charged with being a felon in possession of a firearm and carrying a concealed weapon, but at the end of the trial it was stipulated that “the County Attorney’s Office is still empowered to file said charges.”
Before the trial commenсed, defense counsel made a motion in limine to forbid the State’s witnesses from using the words “polygraph” or “polygraph room” in their testimony. The motion was sustained and the county attorney was ordered to advise his witnesses to use the words “interview” or “interview room” in their testimony. During the trial Detective Van Butsel used the words “polygraph room” twice in his testimony. At a hearing on the defendant’s motion for a mistrial, Van Butsеl testified that he had not been told by the county *889 attorney to not use those words. The motion for mistrial was overruled.
At trial the defendant’s counsel offered evidence of other robberies.which had occurred in Lincoln while the defendant was in jail and unable to post bond. The method of operation used in these robberies was similar in nature to the Burger King robbery. A motion in limine by the State to prevent the intrоduction of this evidence was sustained.
After arraignment, the defendant waived a preliminary hearing in exchange for the county attorney’s promise to turn over all police reports concerning the robbery. At the sentencing hearing in August 1980, defense counsel discovered, from the presentence report, that he had not received a number of police reports, some of which contained material which he thought was exculpatory. Sentencing was deferred, and a motion for new trial based on newly discovered evidence was filed. After a hearing on the motion, the motion was overruled.
In his first assignment of error the defendant contends the trial court erred in sustaining the State’s motion in limine regarding evidence of similar, unsolved robberies in Lincoln which were committed while defendant was in jаil and unable to post bond. The defendant argues this evidence was admissible to show lack of identity because “nearly identical robberies” were being perpetrated while the defendant was in jail.
The evidence offered related to robberies at Taco John’s and Marion’s liquor store in Lincoln, Nebraska. These robberies were committed by two black men, one tall and one short, near closing time, and in each robbery the shorter man took the money. At the hearing on the motion, the witnesses to the Taco John’s robbery were unable to give as complete a description of the robbers as was the witness to the Marion’s robbery. The evidence is that the robbers at Taco John’s did not wear masks, although they did at Marion’s.
*890
The State argues that the subsequent robberies were too remote in time or not sufficiently similar to the Burger King robbery for the evidence to be admissible. Generally, it is within the discretion of the trial court whether evidence of other crimes is admissible.
State v. Ellis,
In determining whether evidence of other crimеs is admissible, important considerations are remoteness in point of time and unique, almost “signature-like” similarity between the charged crime and the other crimes.
Commonwealth v. Murphy,
In his second assignment of error the defendant contends the trial court erred in failing to declare a mistrial when the State’s witness, Van Butsel, twice used the term “polygraph room” in describing where the gun was found which Hippie had hidden in the rеstroom at the police station. The defendant argues that the jurors could have inferred that Hippie had been in the polygraph room, or had taken a polygraph examination. Aside from describing the basement restroom as near *891 the polygraph room, Van Butsel’s testimony in no way connected Hippie with the polygraph room. Although Van Butsel testified that he had not been told of the court’s order in limine, neither Van Butsel’s testimony nor that of any other witness placed Hippie in the polygraph room, or in any way indicated that she had taken a polygraph examination. The violation of the order did not result in substantial prejudice to any of the defendant’s rights.
The defendant next contends that a new trial should have been granted because the State failed to disclose statemеnts made by Kevin Ginger, in direct violation of the court’s pretrial order; because the State failed to disclose “exculpatory” material contained in police reports regarding two black males in a blue station wagon who had been hanging around the Burger King restaurant for 2 days prior to the robbery; and because of information regarding Shelley Snyder’s possible complicity in the robbery of the Burger King.
The statements of Kevin Ginger, which were not furnished to the defendant, contained a version of events taking place immediately before the robbery which was substantially at variance with the testimony of Hippie.
The reports concerning the blue station wagon and the possible complicity in the robbery by Shelley Snyder, a Burger King employee, were not in the possession of the county attornеy until the sentencing hearing, 4 months after trial.
Although Kevin Ginger’s statement contained in the police report conflicted with Hippie’s testimony, it implicated the defendant in the Burger King robbery. In
Evans v. Janing,
In
United States v. Agurs,
Hippie’s out-of-court statements made prior to trial contained a number of inconsistencies as compared to her testimony at trial. She was cross-examined thoroughly as to them by the defendant’s counsel in an attempt to impeach her credibility. When the record as a whole is сonsidered, the evidence against the defendant was substantial. We do not believe the suppression of the police report containing the statements of Ginger was prejudicial to the defendant.
As to the other “exculpatory material” contained in the police reports, the parties admit that the county attorney did not have these reports in his possession until long after trial. Thе information about the blue station wagon and the possible complicity of Snyder were early leads which the police abandoned. In
Moore
*893
v.
Illinois,
The defendant’s fourth assignment of error is that the trial court erred in not granting a new trial because of the State’s failure to disclose the true nature of the plea bargain made with Elizabeth Hippie in exchange for her testimony. This assignment is argued in conjunction with the assignment that the trial court erred in not granting a new trial because of “prosecutorial misconduct in presenting the testimony оf Elizabeth Hippie as true, when the prosecutor knew that she had failed a polygraph examination regarding her involvement in the robbery.”
The defendant contends that conflicting statements made by the county attorney as to the extent and nature of Hippie’s plea bargain constituted “false evidence” knowingly presented by the State.
Of the charges which could have been filed against Hiрpie, robbery and use of a firearm had definitely been dropped in exchange for her testimony. As to carrying a concealed weapon and felon in possession of a firearm, the parties stipulated that the county attorney was still empowered to file those charges against her. If this constituted “false evidence,” any error was waived by the stipulation.
The defendant contends the county attorney incorrectly stated the nature of immunity available under Nebraska law in his closing argument and that this was
*894
prejudicial to the defendant. We believe the allusion to “use immunity” in the final argument was not prejudicial. In
Kennedy v. State,
The defendant also contends that the prosecutor knowingly presented false evidence by allowing Elizabeth Hippie to testify when he knew that she had failed a polygraph examination on the night of her arrest. After taking the polygraph examination, Hippie changed her story and admitted her participation in the robbery, which she had denied while taking the test.
The testimony Hippie gave at trial included her acknowledgment of her own participation in the robbery. The only time she denied her participation was before and during the polygraph examination on the night of her arrest. The same night, she admitted her own participation and continued to do so from then on.
As was noted in
State v. Oglesby,
*895 The defendant’s sixth assignment of error is that the trial court erred in not granting a new trial because of “prosecutorial misconduct in repeatedly vouching for the credibility of Elizabeth Hippie during questioning and during his statements to the jury.”
The сounty attorney elicited from Hippie the fact that she understood that testifying for the State in this case meant giving testimony against the defendant, and that she understood that she was not immune from prosecution for perjury. In his closing argument the county attorney again noted that Hippie was not immune from prosecution for perjury. The defendant contends this testimony and the closing remarks amounted to the рrosecutor “vouching for the credibility” of Hippie’s testimony.
Kennedy v. State, supra,
states at 175,
The defendant’s final assignment of error is that the District Court erred in imposing consecutive habitual criminal sentences of 10 years on both counts when the two crimes arose out of the same incident. His argument is that the use of a firearm in the commission оf a felony statute, Neb. Rev. Stat. § 28-1205 (Reissue 1979), is an enhancement statute, and that by finding the defendant to be an habitual criminal as to both the robbery and the firearms-use statute, the defendant’s sentence was doubly enhanced. The defendant likens the situation to the statute which makes third-offense driving while intoxicated a felony, while the first two offenses are *896 misdemeanors. Neb. Rev. Stat. § 39-669.07 (Reissue 1978).
The fallacy is in the defendant’s argument that his sentence is being “doubly enhanced for one offense.” Section 28-1205, which forbids the use of a firearm in the commission of a felony, specifically states: “(3) The crime defined in this section shall be treated as a separate and distinct offense from the felony being committed . . . .” Even though the two charges of which defendant was convicted arose out of the same transaction, they were separate and distinct offenses. The defendant’s “double enhancement” argument is without merit, and the sentence was proper.
The judgment of the District Court is affirmed.
Affirmed.
