OKLAHOMA CITY (AP) — The high-profile case of a former Oklahoma City police officer convicted of raping women while on duty focused the public's attention on the problem of sexual misconduct on the force, but his appeal raising questions about DNA evidence is playing out in secret. Daniel Holtzclaw, now 30, was sentenced to 263 years in prison for preying on black women he encountered while patrolling poor neighborhoods of the city in 2013 and 2014.
