OKLAHOMA CITY — After four days of deliberations, jurors found a former Oklahoma City officer guilty on 18 charges, including first-degree rape.

Daniel Holtzclaw, who turned 29 on Thursday, was accused of sexually abusing 13 women while on patrol.

Jurors had spent more than 40 hours deliberating his fate.

Jurors told Judge Timothy R. Henderson that they believed Holtzclaw should serve 263 years in prison. Ultimately, Henderson will sentence Holtzclaw at a later date.

Holtzclaw faced three dozen charges stemming from allegations he coerced women to expose themselves, touched them inappropriately or forced them to have sex. The 36 counts include rape, sexual battery, forcible oral sodomy and indecent exposure.

Holtzclaw’s attorneys wanted jurors to believe he was a vigilant, honest police officer who may have violated some department policies but didn’t commit any crimes. The women who accused him, they argued, were just the opposite — addicts, prostitutes and felons who fabricated stories about Holtzclaw. Most of the accusers, they noted, didn’t come forward until approached by police.

Prosecutors, meanwhile, painted Holtzclaw as a dishonest cop who violated his oath to protect the public and instead used his power to “prey on women” who lived in the northeast side of Oklahoma City. He selected victims with criminal histories, they said, and used his power to intimidate and bully them into silence.
