The couple's children — a 1-year-old boy and a 4-year-old girl, plus a teenager who Mike Miller had from a previous relationship — have been in foster care since Friday, court documents show.

Rachel Zuber said she met Kelsey Miller through an online group of friends who all had 4-year-old children.

“We are all so saddened by her loss and, unfortunately, not surprised by the circumstances,” Zuber said in an email. “We are anxious for her to have justice. For her and her beautiful children.”

In a probable cause affidavit filed Friday, police indicated they had been contacted by an advocate for domestic violence victims who said Kelsey Miller had sought services related to an alleged pattern of ongoing abuse. She had bruises on her neck and told police she'd been choked by her husband and was afraid of him, the affidavit says.

"The victim went missing shortly after seeking services," police said in the court document.

Kelsey Miller had not reported any assaults to police, Peschong said, but investigators learned that Mike Miller may have attacked her in the past.
