After a jury trial, appellant was found guilty of rape in violation of D.C.Code 1973, § 22-2801. The principal issues on appeal are: (1) whether the trial court abused its discretion by not excusing a juror after the court learned that the juror knew а key government witness; and (2) whether the trial court erred by refusing *812 to conduct a “Jencks” 1 hearing before a government witness on cross-examinаtion was asked if he recorded any statement by the complainant. We reverse.
At the beginning of the trial, there wаs some confusion as to which courtroom would be used. As a result, during voir dire the potential government witnesses were not present and the jurors, before they were empanelled, did not have an opportunity to see the witnеsses. The jurors were supplied the witnesses’ names and addresses, but none of the jurors recognized any of them. 2
During the trial however, as soon as Mr. Fred Brown, complainant’s boyfriend, took the stand to testify, a juror, Miss Emma Saunders, informed the сourt that she knew him. The trial judge, in response to defense counsel’s request that the juror be excused, said he would dеfer any action at that time but stated that he would substitute the alternate juror for Miss Saunders at the conclusion of thе trial.
The next day, however, another juror was forced to discontinue her service on the panel becаuse of an ankle injury. The court then conducted an inquiry into Miss Saunders’ relationship with Brown, at which time she revealed thаt she had been a personal friend of his mother for some 30 years although she had not seen her in 5 or 6 years. 3 In additiоn, she said that she had known Fred Brown since he was a boy but had not seen him in several years. During the inquiry, Miss Saunders stated that she bеlieved she could be an impartial juror. The court denied the defense’s motion to excuse the juror and the trial continued. Ultimately, the appellant was convicted.
A trial judge, of course, has broad discretion in deciding whеther to excuse a juror for cause.
United States v. Grant,
Impartiality, however, is a state of mind and cannot be measurеd on the basis of any technical formula.
Irvin v. Dowd, supra
at 724,
Here, the juror and the government witness were more than mere acquaintances. The juror had been a personal friend of the witness’ mother for thirty years and had known the witness as he was growing up. Equally significant is the fact that Brоwn’s credibility was crucial to the government’s case. His testimony corroborated the fact that the complаinant reported the incident immediately, and his testimony that she was very emotional when he saw her after the incident also supported her version of the events. If Miss Saunders, in assessing Brown’s credibility, relied upon facts that she had leаrned through her prior relationship with him or his mother, then the appellant would be denied a fair trial. “[A juror’s]
*813
verdict must be based upon the evidence developed at the trial.”
Irvin v. Dowd, supra
The appellant next claims that the trial judge erred by not allowing counsel to conduct a heаring, out of the jury’s presence, to determine whether Officer Horton had taken any “Jencks” notes. We disagree.
Mеtropolitan Police Officer Alfred Horton was the first officer to respond to a report of an assault and, upon learning that the complaint concerned a rape incident, called Detective Frederick A. Cain of the sex squad who, in turn, asked Horton to bring the complainant to his office. In all, Officer Horton was with complаinant about 20 minutes and during this time, Horton testified, he did no more than get complainant’s name and date of birth 5 and transport her to the office of the sex squad.
We hold that a Jencks Act
6
hearing out of the jury’s presence only is required after direct or cross-examination of the witness reveals at trial that he rеcorded a statement.
See United Statees v. Hilbrich,
Appellant’s claim that he should be allowed to cross-examine government witnesses about the $10 witness fee received from the prosecutor is without merit, particularly since a stipulation hаd been entered pre-trial that each government witness was paid a $10 witness fee pursuant to D.C.Code 1973, § 15 — 714(a). We аgree with the statement in
United States v. Thomas,
Reversed with instruction to grant a new trial.
