'Human Etch-A-Sketch' tracks runs on GPS to spell out Perry shooting victims' names
An Iowa man is hoping to send a supportive message to Perry through running.
Rik Zortman calls himself a "Human Etch-A-Sketch" — he runs using a GPS tracker to trace names, primarily of children fighting cancer.
It started with his son's name, Armstrong, who died in 2009.
Since then, he's traced 3,500 names.
Thursday, the day 11-year-old Ahmir Jolliff was laid to rest, Zortman spent the chilly day running for those wounded or killed in the Perry school shooting. Jolliff was killed and Marburger, along with six others, were wounded.
In total, Zortman ran more than 15 miles Thursday through the streets of Perry.
