Otte was involved in a lawsuit challenging the constitutionality of Ohio's execution procedures, alongside fellow death row inmates Ronald Phillips and Raymond Tibbetts, which would ultimately be dismissed in late June 2017.

These included claims that Ohio's lethal injection protocol violated the Eighth Amendment, and that his age at the time of the killings would make his execution unconstitutional.

In an order published by Ohio Governor John Kasich on May 1, 2017, Otte's execution was rescheduled from June 13, 2017, to September 13, 2017.

[4] Following the denial of all his last minute appeals, Otte was executed as scheduled on the morning of Wednesday, September 13, 2017.

For his final meal, Otte ordered and received a mushroom and Swiss cheeseburger, a double cheeseburger with lettuce and tomato, mozzarella sticks, jalapeno poppers, Miracle Whip, a quart of Heath Bar ice cream, two doughnuts, slice of banana cream pie, and soda.
