A Tucson man who stood as a lookout during a home invasion was sentenced to two years in prison on Monday.

Joey Luis Grajeda pleaded guilty to aggravated assault for his role in a 2012 home invasion on the northwest side.

Deputy Pima County Attorney Rona Kreamer argued for a harsher sentence, saying the victim of the home invasion was injured in the crime and feared for his life.

“This was a violent home invasion,” Kreamer said, adding that Grajeda acted as the lookout while two other men beat and robbed the victim.

Grajeda’s defense attorney said his client had inadvertently gotten involved in the crime.

“My client genuinely believed he was going with his father to find some yardwork,” defense attorney John O’Brien said.

O’Brien laid the bulk of the blame on Grajeda’s father, who has likely fled the region and is yet to be arraigned. He said Ernie Gilbert Grajeda and another man initiated the home invasion without Joey Luis Grajeda’s knowledge.

Pima County Superior Court Judge Deborah Bernini gave Joey Luis Grajeda the lightest sentence allowable under the terms of the plea agreement.

Bernini said the defendant’s lack of a criminal history and that he grew up in a dysfunctional family environment were mitigating factors.
