Helen Markham was in the Oak Cliff area when she saw Dallas Police Officer J. D. Tippit being shot. She later described the killer as being short and somewhat on the heavy side, with slightly bushy hair." Later, Markham identified Lee Harvey Oswald in a police lineup, but this was after she had seen his photograph on television.
Although considered the star witness, her testimony was full of mistakes. She said he was alive when the ambulance arrived, but the other witnesses say he died immediately. She also falsely claimed that for the first twenty minutes she was the only person to attend the body. Once again, the other witnesses disagreed with her.
The Warren Commission particularly used her testimony to charge Lee Harvey Oswald with the policeman's murder.
But Helen Markham's testimony is quite incoherent... if not dishonest. For instance, she denied before the Warren Commission having ever talked to Mark Lane. But the latter had recorded their conversation, so Helen Markham had to admit she had lied.
