In State v. Ford, 230 Conn. 686, 692, 646 A.2d 147 (1994), some of the threatening telephone calls to a witness to a robbery came from the cell block where the accused was being held. It was not known which person out of all those persons in the defendant's cell block had made the threat. The evidence demonstrated that the caller, who was not the accused, had more than casual knowledge of the accused's case. The Court in Ford concluded that the jury reasonably could have inferred that the accused intentionally gave information to other inmates to solicit their assistance. Id., at 694. In Ford, the defendant had a motive to threaten, and the principal in the crime had knowledge most probably learned from the defendant. The victim's telephone number to which a threatening call had been made, was not generally known.
