WATERLOO - Authorities still don't have an official cause of death for a young Waterloo woman who died following an assault in a convenience store parking lot.

Today marks one week since 18-year-old Jasmine Janese Mills died at Covenant Medical Center.

On Wednesday, police said the results of an autopsy that was performed Dec. 12 by the Iowa State Medical Examiner's Office are pending further tests.

Waterloo Police Capt. John Beckman said it is possible it will be several more days before medical examiner's probe is complete.

He declined to disclose the nature of the pending tests.

Mills, a mother who worked as developmental assistant at a health care facility, was assaulted while she was with acquaintances in the parking lot of the Kum & Go store on San Marnan Drive in the early morning hours of Dec. 11.

She went to her home on nearby Ravenwood Road, and her friends took her to the Covenant emergency room after determining she needed medical attention.

Hospital staff performed CPR on Mills when she arrived, and she was later pronounced dead, according to the police report.

Police have said the attack didn't appear random and Mills and her acquaintances may have known the alleged assailant.

In another matter, officers were sent to a disturbance at Mills' funeral Tuesday. But when officers arrived there was no fight, and no one wanted to pursue charges, Beckman said.

Officers did provide a traditional police escort to the burial plot at Garden of Memories Cemetery.
