Also killed were Debbie Serecky, 51, of Aurora, and her best friend, Patricia Guntharp, 49, of Centennial.
On the day he died, Marten had ridden a bike by himself for the first time.
Marten also loved cars, trains, airplanes and pushing buttons - buttons in an elevator or on a car console or anywhere. And tickling.
