The judge in the stabbing death trial of an Oak Forest High School graduate grew momentarily impatient Monday after both the prosecution and defense agreed to, once again, delay the start.

"It's really getting overripe here," Cook County Judge Frank Zelezinski said.

This is the fourth delay to the start of the trial for Derek Grib, who is accused of stabbing and killing 18-year-old Felix Jimenez at a party in 2009. The judge originally set the trial for Oct. 18. It was then delayed to November, and again to February, before it was pushed to Monday morning.

In a Markham Courthouse courtroom, the prosecution told Zelezinski there was a scheduling issue and that they wished to delay until July 12. That day will mark the three-year anniversary of the stabbing.

Grib faces first-degree murder charges in Jimenez’s death and aggravated battery charges in the stabbing of another teen at the same party. His attorney plans to argue that he acted in self-defense.

Jimenez was a graduate of Oak Forest High School and had aspirations of joining the military.
