A 31-year-old former Minnesota woman found slain in her suburban Phoenix home suffered serious head trauma, and her body was lying in a pool of blood, according to documents released Friday.

The latest court records revealed new details about the killing of Allison Feldman, a saleswoman for a medical-device company who was found dead Feb. 18 at her house near bustling Old Town Scottsdale.

Feldman, a Minnesota native, graduated in 2001 from Minnetonka High School, where she was a part of the dance line and a cheerleader for hockey, baseball and football.

Her father, Harley Feldman, of Excelsior, has said the family didn't know of anyone who would want to hurt her.

Police previously had withheld many details of the case, including the woman's cause of death, whether she was sexually assaulted and whether any belongings were missing from her home.

According to the search-warrant affidavit, Feldman's boyfriend found her nude with a cloth wrapped around her head. He then went outside and called 911.

First responders found Feldman had "cranial trauma" and pronounced her dead. They also discovered a white substance around her body and smelled a bleach-like odor, the documents said.

The records show a surveillance camera from a nearby home confirmed the boyfriend's account of his arrival at the residence. Police have not said he's a suspect.

In papers filed Feb. 19, a detective said investigators were seeking a warrant to monitor another person who had contact with Feldman in the past.
