According to a booking sheet, police determined that Cerenil's significant other, Charles Rees Karn, had pushed her, causing her to strike her head on a table near the bed and lose consciousness.

Cerenil was taken by ambulance to Cheyenne Regional Medical Center, where she died Saturday afternoon.

Karn was arrested and charged Friday with aggravated assault, strangulation of a household member, and domestic battery, but could now face a homicide charge.

He's currently being held in the Laramie County Detention Center on a $25,000 cash bond awaiting a June 23 preliminary hearing.
