Court documents say police were called to Collier's Ferry Park on Pine Street in Beaumont on June 24, 2017, about a woman's body found by callers. 

Dungan's body was found, with her hands tied behind her back, with obvious signs of sexual assault according to a probable cause affidavit. 

The affidavit says the preliminary autopsy report showed she died from manual asphyxiation by homicide.

A witness at the park told investigators she saw a small silver car at the scene before the body was found according to court documents. 

Investigators later found from store video from Calder Food Mart that Dungan had been seen getting into a small silver car, later identified as a 2005 Ford Focus that came back to Coleman's mother. 

An employee at the gas station told investigators she saw the woman getting into the small silver car with a man according to the documents. 

Coleman was later identified from a photo line-up as the person who was seen driving off with Dungan before her death according to the documents.
