Summitt v.
Bordenkircher, 608 F. 2d 247, 250 (CA6 1979). In addition, the Commonwealth of Kentucky, where petitioners were tried and convicted, appears to require a hearing out of the presence of the jury, upon defendant’s motion, for confession and for search evidence. See Ky. Rule Crim. Proc. 9.78. In addition,
Moore v.
Commonwealth, 569 S. W. 2d 150, 153 (Ky. 1978), decided after petitioners were convicted, held that the trial court’s refusal to hold a suppression hearing to determine the admissibility of identification evidence constituted error. Previous Kentucky appellate decisions had reached a similar conclusion.
E. g., Francis v.
Commonwealth, 468 S. W. 2d 287 (App. 1971).
