The woman told police that after she stopped the vehicle on the side of the road, Hillard began stabbing her with a steak knife and continued to stab her after she exited the vehicle. Witnesses driving along the interstate stopped to offer assistance to the woman, and Hillard leapt from a bridge into the Oklahoma River. The man was pulled from the river, taken to a hospital and treated for his injuries, and then transported to the Oklahoma County Jail. The woman sustained injuries to her arm, shoulder, finger, knee, and ear. She told police that she is eight months pregnant and that Hillard is not the father of her unborn child. At the time of the alleged incident, Hillard was out of jail on bond after an arrest on two arson complaints earlier this month. He also remains on probation following a 2009 youthful offender conviction of armed robbery and conspiracy to commit a felony. In that case, he entered a blind guilty plea and was sentenced to 12 years for armed robbery and 10 years for conspiracy with all suspended but the first 8 years and both sentences to run concurrently. According to Oklahoma Department of Corrections records, he was incarcerated from February 3, 2010 through July 16, 2014. He is to remain on probation for armed robbery through December 10, 2021; however, in light of the current charges against him, it would not be unusual for the district attorney to file a motion to revoke the suspended sentence and order him back to prison. As of this writing, he is held in the Oklahoma County Jail on complaints of first degree arson and domestic assault and battery with a dangerous weapon. First degree arson is defined by state law as "willfully and maliciously" setting fire to an occupied structure. It is also considered to be first degree arson if a person causes a fire or causes a person to be burned in the manufacture of a controlled substance, as in the case of a meth lab fire or explosion. First degree arson is a felony punishable by a maximum of 35 years in prison. Domestic assault and battery with a dangerous weapon is a felony that carries a maximum sentence of 10 years in prison.
