Lane faces a maximum sentence of life in prison without parole if convicted. He isn't eligible for the death penalty because he was 17 at the time of the shootings.
The school district plans to commemorate the anniversary of the Feb. 27 shootings with service projects and other events, including a memorial walk to the town square by students, staff members and first responders.
One of the shooting survivors, 17-year-old Nate Mueller, says the tragedy has motivated him to lobby for gun safety, which he did during a recent trip to Washington. Mueller told WEWS-TV on Friday that surviving a bullet that grazed his ear prompted his involvement in the issue and that he feels it's his duty.
