The mystery surrounding Meighan Cordie's final hours only intensified this week after a prosecutor ruled her death was accidental but released a memo that outlined glaring inconsistencies in a story provided by her mother.

Cordie’s mother, Jennifer Weathers, failed to share everything she knew about the case when she made a missing persons report to a non-emergency dispatcher on Aug. 19, the day after Cordie went missing, according to information provided by Yamhill County District Attorney Brad Berry.

In a recording of the call, Weathers told the dispatcher that she was “kind of worried” because she hadn’t seen her daughter since the night before.

Weathers sounded baffled, saying she and her 27-year-old daughter had been at a wedding in rural Yamhill County. She said her daughter “was upset and got out of the car, and I haven’t heard anything since.”

Cordie's body was found down an embankment on Aug. 23 by joggers along Southeast Foster Road in Dayton, nine miles from where Weathers reported on the call that her daughter had left the car near the wedding. Berry said he believes Cordie either jumped or fell out of her mother's moving car.

An autopsy showed that she suffered two broken or severed vertebrae and died instantly upon hitting the roadway.

In the call to dispatchers, Weathers said she checked hospitals and jails for her daughter, to no avail. She said she drove around for two hours that morning looking for her daughter but couldn’t find her.

Weathers didn't tell the dispatcher that she and her daughter had gotten into an argument and physical fight -- with Cordie pulling out a clump of Weathers' hair.

Weathers came forward about the “physical nature” of the argument only after a sheriff’s detective confronted her with the clump of hair that had been found in Weathers’ car, according to a decline-to-prosecute memo written by Berry.

Berry announced at a news conference Thursday that his office wasn't pursuing homicide charges against Weathers, citing a lack of evidence supporting that theory. But his office is charging her with driving under the influence of intoxicants and recklessly endangering another person, he said.

Berry noted that some parts of Weathers’ story “still did not make sense.”

Berry also said he found it “disconcerting at best” that Weathers said she took a muscle relaxer the night before she took her first polygraph test. The test was postponed to the afternoon, and the results were inconclusive.

Weathers didn’t show up for a second polygraph test and has recently failed to cooperate with investigators, Berry said.

During the call to the dispatcher, Weathers simply said her daughter "got out of" the car. Weathers later told investigators that her daughter actually jumped out as Weathers drove less than 5 mph a short distance after leaving the wedding, according to Berry's memo.

But the prosecutor concluded that the car had to be moving much faster than that to explain Cordie's extensive injuries.

Another inconsistency: Cordie was barefoot when she left the car and her body was found more than nine miles from the site of the wedding -- “yet her feet did not have injuries consistent with having walked over 9 miles without shoes on,” the prosecutor said. Berry concluded that Cordie couldn't have been where Weathers said she was when she fell or jumped from the car.

Weathers is scheduled to appear in Yamhill County Circuit Court on Wednesday to hear the DUII and reckless endangering charges against her.

Prosecutors, however, could have a challenging time proving the DUII case -- because police didn’t stop her and administer field sobriety tests or test her blood alcohol content that night. The case might have to rely heavily on witnesses, who authorities say recounted how Weathers appeared too intoxicated to be driving away from the wedding that night.
