An autopsy report released by Winnebago County Coroner Bill Hintz Thursday shows that 16-year-old Rebecca Finkenhofer died from multiple stab wounds and blunt force trauma.
The Winnebago County Sheriff's Office says Finkenhofer did get shot as well, but the Hintz says the cause of death is linked to the stabbing.
Rebecca's 63-year-old grandmother Cheryl Puckett was also shot during the incident. The grandmother suffered a gunshot wound to the face while she was inside the apartment and is being treated for life-threatening injuries at the University of Wisconsin-Madison Hospital.
Police say the suspect, Michael Mernack, 36, was shot by deputies shortly after they arrived on the scene. They say they found him armed with a gun outside the apartment when they arrived.
Mernack is being treated for life-threatening injuries at a Rockford hospital. He is in the ICU.
