Attorney: Mark Grace looking at time in prison

Arizona Diamondbacks broadcaster Mark Grace was arrested for a DUI on Thursday night and he could be looking at an extended stay in prison.

After consulting with a Valley attorney, KTAR has learned that if Grace is convicted of his second DUI within the past seven years, that he would be sentenced to a mandatory 90 days in jail, 60 of which could be suspended if he attends alcohol classes.

If Grace is convicted of an aggravated DUI, a felony, he would get prison time, though it is unclear how long he would be sentenced to, as the time given is dependent on numerous variables. The average sentence in these cases is 2.5 years.

When police made contact, they determined that Grace was driving without his interlock device, which is a Class 4 felony. A conviction of driving without the required interlock carries a prison sentence of one year to 3.75 years, followed by probation.
