UPDATE: Woman who died from alleged domestic violence had protective order

UPDATE (3:44 p.m. 5/8):

An interim complaint obtained by KGUN 9 gives more detail on the domestic violence incident that left 73-year-old Susan Ainsworth Gustafson dead.

According to the complaint, Gustafson called 911 on April 29. Gustafson and her partner, John Sullivan had been in an argument, and the person who took the call could hear Gustafson tell Sullivan, "I will tell them that I fell."

The responding officer heard the commotion, knocked and announced, but no one answered. Sullivan answered the door and officers saw Gustafson with cuts to her face and bruising.

Investigators saw cuts around Susan's eyes and on her lip. The cuts would require several stitches, the complaint said.

Gustafson started experiencing chest pains. She was transported to UMC for evaluation, the complaint said. AT UMC, Gustafson was treated for a heart attack. Gustafson told staff that Sullivan assaulted her, the complaint said.

A records check showed that Gustafson had an order or protection against Sullivan.

The complaint said, post-Miranda, Sullivan said he loved Susan, that he was drinking all night, but not enough to make him intoxicated or incapacitated. He told investigators Gustafson was belligerent toward him and mentioned the order of protection.

Sullivan said he was rough on Gustafson and punched her less than ten times. He said he knew about the order of protection and would've run from officers.

Gustafson died in hospital. According to the medical examiner, she died due to a heart defect and the assault from the incident.
