A 30-year-old carpenter, whose 1980 conviction for the rape of a Takoma Park woman on two separate occasions was reversed by the Maryland Court of Appeals, has been convicted in a new trial by a Montgomery County Circuit Court jury.

Harry S. Orloff Jr., who was convicted late Wednesday night by a 10-woman, two-man jury in an eight-day trial, was first convicted on April 2, 1980, on charges of raping a 22-year-old Takoma Park woman on April 21, 1979, and returning to her home and sexually assaulting her again on June 23.

Orloff appealed his conviction and the Maryland Court of Appeals granted him a new trial on the grounds that the state's attorney used evidence from the second incident to establish that Orloff was the man who had committed the rape two months earlier.

In the new trial, which consisted only of the June incident, Assistant State's Attorney Matthew I. Campbell contended that Orloff entered the victim's first-floor apartment through a window and forced her to have oral sex with him. Campbell told the jury that police found five sets of Orloff's fingerprints left on the window as he entered the apartment and a sixth set of prints left on the window sill as he departed.

In his testimony, Orloff denied that he ever entered the woman's apartment. He told the jury and Judge Richard Latham that he might have touched the window sill while he was waiting for his clothes to wash in a laundry near the building.

Defense attorney Thomas P. Moran called six character witnesses, including Orloff's former girlfriend and his former wife, to testify that Orloff was a nonviolent and kind person who respected women.

But on cross-examination, Orloff's former wife told the jury he beat her regularly and forced her to have sex with him after the beatings.
