 Investigators have ruled a deadly house fire in the Town of Clayton a murder-suicide. 

On Tuesday,  the Winnebago County Sheriff’s Office in conjunction with the State of Wisconsin Division of Criminal Investigation and the Winnebago County Coroner’s Office, completed the investigation into the deaths of 27-year-old Ashley Mielke and 38-year-old Jeremy Wallenfang, whose remains were located in the burned rubble.

Investigators say Jeremy Wallenfang shot and killed Ashley Mielke, set  the house on fire, and then shot himself in an apparent murder-suicide.

According to witness statements, Mr. Wallenfang had threatened to kill Ms. Mielke and burn the house to the ground in the months leading up to this tragedy.

The last known contact with Mr. Wallenfang was a voice message he left for a family member approximately two hours prior to the house fire being reported.

The family member summarized that Mr. Wallenfang said, “You’re going to be mad at me and to tell my daughter that I love her.”


UPDATE: 5/8/19 11:18 a.m. 

The Winnebago County Sheriff’s Office has identified the human remains found inside a home after a fire in the Town of Clayton. 

The first person has been identified as 27-year-old Ashley M. Mielke of Appleton. The second is 36-year-old Jeremy M. Wallenfang of Neenah, according to the Winnebago County Sheriff’s Office. 

The incident happened on May 1, 2018, at 3302 Breezewood Lane. 

Because of the severity and intensity of the fire, the remains are significantly degraded, and the causes of death for both are still considered to be undetermined at this time, according to the sheriff’s office. 

The multi-faceted investigation is currently active and ongoing. 

“Our thoughts and prayers remain with the families and friends of the deceased,” Winnebago County Sheriff’s Office said in a statement.

When we initially responded to the scene, it was reported that there were two people unaccounted for.

Until the Sheriff’s Office is able to positively identify the remains of those two people, the original attempt to locate and use caution for JEREMY WALLENFANG will remain active.
