Dawna Natzke was killed in December 2011.
Kevin Duck was arrested several weeks after Dawna's death for violating probation, according to arrest reports, but he was later released. He was only named as a person of interest.
Garland County Prosecutor Steve Oliver said the warrant was issued Monday on a first-degree murder charge for Kevin Duck in Dawna Natzke's death.
Natzke was last seen December 21, 2011, leaving a holiday party with Duck. Her body was found New Year's Eve in a remote area in the Ouachita National Forest.
Duck told detectives in 2011 that the couple returned to Natzke's home after the party and that she was gone when he awoke the next morning.
The arrest affidavit for Duck mentioned that Duck had called in to his employer saying that he would be late for work the day after Natzke went missing. His employer, Lester Woodson, mentioned to authorities that Duck had said he was looking for Natzke that morning but never asked for time off to do it again.
Duck's arrest affidavit also mentioned one of Natzke's friends, Patty Hathaway, witnessing Duck and Natzke leave the Christmas party together and in the process saw Duck push Natzke out the front door. Hathaway had sent Natzke a text the night before saying she didn't like what she had seen and the next day a response from Natzke's phone read, "He did not push me. I fell and he caught me. I had taken a pain pill and was tour up."
Hathaway didn't believe that text was from Natzke since it was not her style of texting and mentioned that she would have called instead of texting back.
Cell phone records are what eventually linked Duck to the crime. At 9:02 AM on the day Natzke disappeared, a call was made from Duck's cellphone that originated 6/10ths of a miles from the locations where Dawn's car was found burning.
An autopsy on Natzke's body showed she had died within three to four hours after leaving that party since her blood alcohol content level of .07 - according to medical examiner Dr. Charles Kokes. Kokes mentioned that most likely represented antemortem alcohol consumption. Kokes determined Natzke's cause of death to be from blunt force trauma and drowning.
Oliver said Duck is not in custody and is believed to be in another state.
Garland County Sheriff's Deputy Scott Hinojosa told Channel 7 investigators are working with local authorities in another jurisdiction to bring Duck into custody.
