United States v. David Roberto Alvarez
458 F.2d 1343
August 31, 1972 · Docket 71-2949
Opinion
David Roberto Alvarez appeals from a judgment of conviction following a trial by a judge sitting without a jury on 11 counts of an indictment charging him with unlawfully conspiring to buy, sell and traffic in narcotic drugs in violation of 21 U.S.C. §§ 173, 174 and 26 U.S.C. §§ 7237(b), 4704(a) and 4705(a). The only issue presented on appeal is whether the government presented sufficient evidence to permit the trial court to find beyond a reasonable doubt that Alvarez was legally sane at the time he committed the offense charged. After a careful review of the record and briefs in this case we conclude that the government met its burden of proof on the issue of sanity and affirm the conviction.
It is undisputed that Alvarez offered sufficient evidence to raise the issue of his sanity at the time of the offense and placed upon the government the burden of proving his sanity at the time of the offense beyond a reasonable doubt.
In rebuttal the government offered the testimony of Dr. Fain who said that based upon his observation of Alvarez at the Medical Center for Federal Prisoners at Springfield, Missouri, he was of the opinion that there was nothing that would indicate that Alvarez did not have the ability to appreciate the wrongfulness of his conduct and to conform his conduct to the requirements of the law at the time of the offense. Two undercover government agents who had entered into narcotics transactions with Alvarez testified. One said that the actions of Alvarez were extremely cautious and somewhat shrewd. The other testified that during the transactions Alvarez was a very careful dealer and the agent considered him to be very smart.
The acknowledged rule in this circuit is that the questions of the credibility and weight of expert opinion testimony are for the trier of the facts, and that such testimony is ordinarily not conclusive :even where it is un-contradicted.
