Bond was set at $500,000 Tuesday for a 31-year-old man charged with aggravated vehicular homicide and operating a motor vehicle while intoxicated in the death of his girlfriend in September 2011.

Ryan Hayes also is eligible for electronic home detention, for which he would have to wear an ankle bracelet, if he posts the cash bond, according to a Montgomery County Common Pleas judge.

Hayes has been indicted on two counts stemming from the homicide and two counts of OVI in the death of Kadriyyah Harvey, 33, also of Trotwood.

Harvey was killed the night of Sept. 17, 2011, when Hayes drove through cautionary signs at Hoover and Goodlow avenues that signaled a road closure and slammed head-on into a large piece of construction equipment.

She was a front-seat passenger.

The signs had been erected months earlier and a police investigation determined Hayes had a blood-alcohol content of .171, more than double the legal limit, the county prosecutor’s office has said.

Hayes, who suffered serious injuries, was taken to Miami Valley Hospital.

Because he was intoxicated at the time of the crash, each count involving the homicide charge is punishable by up to eight years incarceration, the prosecutor’s office has said.
