She lay on the floor all night, unable to move after her roommate allegedly shoved her against the wall, breaking her neck.
Finally, at about 9:15 a.m. Wednesday, her roommate broke down and called 911, police say. The 48-year-old woman was taken to Wesley Medical Center, where she underwent surgery for a broken spine.
Doctors say she will be paralyzed from the chest down for the rest of her life, Lt. Doug Nolte said Thursday.
Investigators say the altercation started at about 11:30 p.m. Tuesday in their apartment in the 4900 block of East Lincoln when the victim's 47-year-old roommate demanded money from her.
She refused, and he shoved her. She fell back against the wall and then hit her head on furniture as she fell, Nolte said.
She immediately lost feeling from her chest down and pleaded with her roommate to call for help. He refused, fearing she would tell police what he had done, she later said.
While she initially told first responders she had fallen, she told people in the ambulance that she had been knocked down.
Her roommate has been booked into jail on suspicion of offenses including aggravated battery, aggravated intimidation of a victim and kidnapping.
