In late February, Hancock, an eighth grader who was 14 at the time, took a relative's gun to his Madison Township, Ohio, school and opened fire in the cafeteria. He shot two classmates while two others were injured from shrapnel. All four students survived and recovered from their injuries.

According to a Facebook post by the sheriff's office, the suspect ran from the scene but was apprehended. Authorities were able to locate the weapon used, the statement says.

"At a press conference that day, Sheriff Richard K. Jones said, "When you see these things, you see them all over the country ... you think they can't happen to you. But they do."

The Associated Press reports that Hancock's lawyer, Charles Rittgers, said Hancock's actions "came totally out of the blue" and that he didn't have a history of being in trouble. The AP reports that Rittgers said Hancock was sorry for what he did and was relieved that nobody was injured more seriously.

"There really isn't a good motive for what he did," Rittgers told the Associated Press. "You're dealing with the mind of a 14-year-old. And as most people know, especially at that age, they're immature and they act sometimes impulsively."

WVXU reports that prior to his plea, a grand jury determined that Hancock is a "Serious Youthful Offender," meaning that he was not tried as an adult but that he would receive a mandatory "blended sentence."

Prosecutor Mike Gmoser tells the station: "The Judge will send the juvenile to State supervision until the juvenile is twenty one years of age followed by a sentence as an adult for a period the Judge will determine."
