Detectives searched the car and reportedly found blood and biological material, along with Williams' items inside.

Ivy allegedly admitted to investigators in Rancine, that he had killed Williams during a physical altercation in St. Louis. Authorities said Ivy then disposed of her body in an unknown location.

He's being held without bond in Rancine, Wisconsin. KSDK reported that Williams family and police are still searching for her body. St. Louis police are also trying to extradite Ivy from Wisconsin.

“It’s devastating. They separated earlier this year. She was trying to co-parent with him, but she had started seeing someone else. I will be okay, but it just hurts for the kids. Her baby boy is not the happy child he normally is because he’s crying a lot. He’s missing his mom. We will keep searching for her body,” Bagley told KSDK.
