delivered the opinion of the court:
Thе minor-respondent, Michael Lane, appeals from the judgment of the trial court in which he was found to have violated his probation and was committed to the Department of Correction. Respondent contends: (1) the State failеd to prove by a preponderance of the evidence that he
Respondent was placed on a one-year probation on December 5, 1974, after having been adjudged a delinquent for the commission of an armed robbery. On September 29,1975, а supplemental petition was filed charging respondent with armed robbery. The same day both sides filed discovery motions which included a request for the names and addresses of anticipated witnesses; the respondent’s motion also requested disclosure of any witnesses “that may be or would be favorable to the defense.” Both parties responded to discovery on the day of the hearing, October 14,1975. One witness was listed by the defense as Glay 1 Phillips, but just prior to trial they informed the сourt that her last name was Green. The State moved to exclude the witness because she was not listed in respondent’s answer to discovery. Defense counsel explained to the court that the witness used both names. Green was her fathеr’s name and Phillips was her mother’s. When counsel interviewed her she gave him the name Phillips. The court excluded the witness on the ground that her name was not on the list of witnesses.
At the hearing Darnell Parker testified that on September 21,1975, he was working as а newsboy. At about 11 a.m. that day he was in the vestibule of a building at 4525 South Michigan in Chicago, preparing a bill for delivery to a customer on the first floor, when a boy walked in with a knife and also pulled out a gun. Parker had just rung a customer’s bell but when she asked who was there the armed boy ordered him not to say anything and then demanded his money. He had put his gun away, but held the knife on Parker. Parker first refused to turn over any money. But after he argued with the boy for 10 to 15 minutes, he gave him some money and the boy reaсhed in Parker’s pocket for the rest and then fled. Parker indicated that the area was lighted and he was face to face with the boy during the robbery. When the police arrived he described the boy as wearing dark pink pants with a blue and brown checked jacket and a dark blue and white hat. He also gave a height estimate, unspecified at trial, and apparently indicated an estimated weight of 185 pounds. He did not describe any of the boy’s facial features to the рolice, nor could he recall any at trial.
On September 28, 1975, at about 9 a.m. Parker was walking past a
Officer Charles Johnson testified that on September 28,1975, Parker informed him that he had seen the person who had robbed him, describing him as a mаle Negro, 5'6", 160 pounds, with a white hat, black jacket, and pink pants. Johnson saw a man fitting this description running north on 43rd Street. The police chased him, but lost him when he ran in a gangway at 4204 South Michigan. They searched the area and found a male Negro lying underneath a stairway at 4204 South Michigan. He was wearing a black jacket and pink pants and a white hat was found near him. Parker identified this person at the police station as the one who had robbed him. At trial Johnson identified the respondent as the man he had arrested. He denied having told Parker that the man who robbed him was at the police station.
Charles Dilyard, a friend of the respondent, testified for the defense that on September 21 he was in his aunt’s apartment at 51st and Fedеral from 10 a.m. until 5 p.m. The respondent and Clay Green were also there, and respondent never left the apartment during that period. Dilyard could not remember what respondent was wearing because he was “half high” on beer; he testified that he might have had six beers.
Respondent testified that he was at the apartment with Dilyard and Green. He arrived there the evening of September 20 and did not leave until 5 p.m. on September 21. He denied robbing Parker but indicated his belief that another boy, whom he named, had committed the robbery. Respondent also testified that on the 21st and 28th of September he was wearing pink pants and a black jacket.
Respondent’s mother testified that her sister lived at 4204 South Michigan, where respondent wаs arrested.
Respondent’s contention is that the testimony of Darnell Parker was highly improbable. Specifically he cites Parker’s testimony that he argued with the person who robbed him for 10 to 15 minutes before relinquishing his money, even though the robber was аrmed with a gun and a knife. Respondent also notes that Parker was unable to describe any of the robber’s facial features. When these factors are considered in the light of the allegedly suggestive show-up at the police station, respondent contends that his delinquency was not established by a preponderance of
However, respondent also complains of actions by the court which prevented presentation of additional evidence by him. We have noted that the trial court barred the testimony of Clay Green as a sanction for not listing her on the list of witnesses. This sanction is one which the trial court, in the exercise of its discretion, may impose when a party has failed to comply with discovery. (Ill. Rev. Stat. 1975, ch. 110A, par. 415(g)(1).) But it is an extremely harsh action, and an inappropriаte use of the sanction may prejudice a defendant and constitute reversible error. (People v. Rayford (1976),
The State contends that the failure of the defense to make an offer of proof concerning the testimony of the witness makes it impossible for this court to speculate on the nature of her testimony and the prejudicial effect of its exclusion. But contrary to the cases cited by the State, in which the reviewing court could not determine with precision the exact nature of the excluded expert testimony (People v. Hahn (1976),
Because of our determination of this issue, we need not discuss
For the foregoing reasons, the judgment of the trial court is reversed and the cause remanded for further proceedings in conformity with this opinion.
Reversed and remanded.
JOHNSON and LINN, JJ., concur.
Notes
The witness spelled her first name in the record as Glay; she was also referred to as Day.
