Cuyahoga County prosecutors asked Common Pleas Judge Dick Ambrose Monday to dismiss the charges on grounds it did not make sense to put the surviving victims through another trial, The (Cleveland) Plain Dealer reported.
Sowell, 52, had been scheduled to stand trial Monday on charges he attacked two more women who testified against him during his eight-week murder trial.
Sowell was convicted July 22 of killing 11 women and hiding their remains in and around his Cleveland home.
He was also found guilty of attempting to kill three other women.
