A jury in Grand Rapids convicted Steven Deuman in September 2012 in the 2011 death of his daughter, Evelynne. The first-degree murder conviction carries a mandatory penalty of life without parole.
The girl died on the Grand Traverse Band of Ottawa and Chippewa Indian Reservation, northwest of Traverse City. An autopsy found she was asphyxiated.
Federal authorities investigated the death because it occurred on tribal land. Deuman and the baby's mother lived on the reservation.
Natasha Maitland said she's burned all evidence that Deuman was ever in her life, and considers her ex-boyfriend a "coward and monster" for killing their baby.
