Opinion OF THE COURT Appellant, Jerome Philip Dutkiewicz, mounts a two-pronged attack on the validity of his conviction by jury for the crime of transporting a stolen motor vehicle across the state lines, 18 U.S.C.A. Â§ 2312. Dutkiewicz's claims arise out of testimony and evidence introduced at trial by Special Agent Eugene Coyle of the Federal Bureau of Investigation. While awaiting trial Dutkiewicz was interviewed by Agent Coyle in the Hudson County Jail on September 14, 1966. At that time appellant first signed a waiver of his Constitutional rights1 and then confessed to transporting a stolen automobile from New Jersey to New York. Dutkiewicz now claims that he was under the influence of narcotics at the time he confessed and was therefore unable intelligently to waive his Constitutional rights. Appellant further contends that his confession was involuntary because it was secured through psychological coercion.
