A 50-year-old Washington man was found guilty yesterday by a D.C. Superior Court jury of defrauding two women of $2,825 in cash and an automobile in connection with a scheme to buy real estate.

The jury of six women and six men convicted Samuel Fowler of eight counts of false pretenses, six counts of grand larceny and one count of perjury after 5 1/2 hours of deliberation. Fowler was acquitted of two other charges of false pretenses.

The offenses took place between September and December 1977 while Fowler was a resident of a halfway house run by the D.C. Department of-Correction, according to assistant U.S. Attorney James F. Hibey. Fowler was on parole at the time for earlier false pretenses and grand larceny convictions, Hibey said.

The government contended that Fowler said he was business associate of U.S. District Judge John J. Sirica and former D.C. Corporation Counsel John R. Risher Jr. in order to induce the women to invest in a corporation to buy real estate in Washington at low prices.

Fowler also told one of the women that he was a former defendant in the Watergate scandal trials and that he was owed $1.5 million in "Watergate funds," the government contended.

Fowler's court-appointed lawyer, former D.C. Superior Court Judge Charles W. Halleck, argued that government witnesses had presented contradictory evidence and said one of the women had lent Fowler money on a personal basis.

Judge Fred L. McIntyre, who presided at Fowler's trial, scheduled sentencing for Nov. 28.
