Can an accomplice be convicted of a crime based on their testimony?

However, section 1111 prohibits a conviction based "upon the testimony of an accomplice unless it be corroborated by such other evidence as shall tend to connect the defendant with the commission of the offense." ( 1111, italics added; see People v. McDermott (2002) 28 Cal.4th 946, 985-986 ["A conviction can be based on an accomplice's testimony only if other evidence tending to connect the defendant with the commission of the offense corroborates that testimony."].)
