A search warrant served in the investigation into the death of 35-year-old Tracy Tribble stated that the autopsy revealed that she was struck with an unknown object that caused her face to fracture.

The Iowa State Medical Examiner's Office indicated to Council Bluffs Police officers that the left side of Tribble's face was fractured and several teeth were missing.

Her husband, Stan, said he last saw Tribble at 6 a.m. on May 3. When he returned home at 5:30 p.m., her car was still in the driveway, but she was nowhere to be found.

Court documents indicated that when Stan Tribble came home he found Tracy's wedding ring and cell phone on the counter, and the couple's dog and cat were missing. Two messages were on the answering machine. One was from the Council Bluffs Animal Shelter informing them that their dog had been found and the other was from a co-worker of Tracy's who Tracy was supposed to pick up that morning.

Stan Tribble told officers that the couple had been fighting recently, but he said that it was always verbal and he never touched her.

The Pottawattamie County Attorney's Office has filed misdemeanor serious assault domestic abuse charges against Stan Tribble. The charges stem from an April 3 incident in which Council Bluffs Police officers were called to the Tribble residence.

Court records stated that Tracy told officers that she and her husband got into an argument and Stan assaulted her.

Stan Tribble told officers that they did have an argument, but denied assaulting her.

Tribble's body was discovered in the Missouri River last Friday. Her death has not officially been ruled a homicide.

The autopsy on Tribble's body was conducted on Saturday at the Iowa State Medical Examiner's Office in Ankeny. Officers are still waiting for the full autopsy report.

During the warrant search on Monday, detectives searched the couple's two vehicles and the home "looking for teeth, hair, fake fingernails belonging to Tracy Tribble."

Officers were also looking for any indication of a struggle in the residence or the vehicles resulting in DNA left behind. Several items were taken from the home during the search, including pillowcases, bedding, a waterbed bladder and lining and one of the vehicles.

Pottawattamie County Attorney Matt Wilber said that until his office has received the formal reports from the medical examiner, he is not commenting on the investigation.

Wilber did stated that although he knows the physical findings of the autopsy, without the formal reports he has no way of knowing the cause of the injuries or the manner in which they were inflicted.

"Getting from point A to point B is not that easy," he said.
