Is the testimony of a single witness sufficient to support a conviction?

As noted above, the testimony of a single witness may be sufficient to support a conviction unless that testimony is physically impossible or inherently improbable. (People v. Young, supra, 34 Cal.4th 1149, 1181.) Minor described a situation where defendant lured her into the garage, away from the house, and while her parents were still in bed. He turned on the compressor to prevent her voice from being heard. He used force to move and turn her around into a specific position, so he could stand behind her as he lowered her shorts and underwear.
