Franklin County Prosecutor Ron O'Brien says he has two weeks to file an answer to the newest motion by the attorneys of Charles McCoy junior, who is accused of being the Ohio highway shooter. McCoy's attorneys filed a motion yesterday to suppress any incriminating statements he may have made after his arrest in March in Las Vegas. The motion argues that detectives didn't permit McCoy to sign a Miranda rights waiver before interrogating him. But O'Brien says the U-S Supreme Court has ruled that a signed waiver isn't necessary if a suspect is read his rights. The 28-year-old man is charged with 24 counts, including aggravated murder, murder and attempted murder. He is accused in a series of shootings, including one that killed a woman and could be sentenced to death if convicted in the slaying.
