Herald Democrat article from 11-29 (Tuesday).
Undetermined if it is a criminal case. Cause of death undetermined so an inquiry has been opened. Autopsy was done in Oklahoma City on Saturday.
The investigation is currently being led by the Bryan County [Oklahoma] Sheriffs Office with assistance from OSBI and the Denison [Texas] Police Department. Andrea Ratliff was reported missing Nov. 22 to Denison Police and her body was found Friday morning in the Red River near Carpenters Bluff Bridge.
Nathan Calloway, an investigator with the Bryan County Sheriffs Office, said the body was discovered at about 10:24 a.m. Friday by a member of a search party. About an hour before the discovery, local residents started a search of the area after Ms. Ratliffs phone was tracked there. Calloway said a teenager discovered the phone near Carpenters Bluff Bridge and found that it belonged to Ms. Ratliff. The phone was then recovered by Denison Police, and the search party was sent to that area.
Her body found in 2-3 feet of water. Airboat used for recovery.
Body identified by family, fingerprints, tattoos, standard protocols.
Water was cool, so not as much deterioration if warmer temperature.
Amy Elliott, a spokesperson with the Oklahoma Medical Examiners Office, said via email that the cause and manner of death are pending toxicology results. The toxicology report can take four to six weeks to complete so the final autopsy report will not be available until then, she said.
Calloway said there is usually a preliminary report available before the final autopsy report. Brown said in the meantime and because an identification has been made, investigators started talking to family and friends to build a timeline of events in the last several days of Ms. Ratliffs life. The timeline would cover who Ms. Ratliff was in contact with, she said.
They don't know how she got to the bridge. They don't know if she died in Texas or Oklahoma. They don't know if her death was suspicious, suicide, or an accident.
They do say she was said to be intoxicated when last known to be seen.

It is a fairly lengthy article. I tried to catch all of the specifics to summarize, but I could have missed something.
I don't anticipate any issues regarding multiple possible jurisdictions in an investigation/inquiry as the agencies involved are probably accustomed to working together.
I have read a couple of articles about her personality and how beloved she was by family and friends.
She worked as a waitress and her employer had wonderful things to say about her.
