The mysterious disappearance and death of a young mother in Alabama may not have been the result of foul play, as authorities previously believed.

As CrimeOnline reported, Daniella Vian, 24, went missing in July 2018 in West Mobile during a night out with friends. She reportedly believed she left her cell phone behind at a bar, and went back for it after stopping at a gas station to search her car for the phone. She was never seen alive again, and earlier this month her car was found with a body inside, submerged in Bayou Sara in Mobile County.

Authorities had previously said Vian’s death was being treated as a homicide. But authorities now believe she may have died accidentally. Mobile Safety Director James Barber told WKRG that the adult woman’s body found in the vehicle did not show any signs of trauma — though a positive identification of the remains has not been confirmed.

Fox 10 also reports that “high-ranking city officials” have said the woman’s death may have been accidental, but did not provide any further details. Toxicology text results are reportedly still pending, and the Mobile Police Department is expected to release further information about the investigation on Tuesday.

CrimeOnline will continue to update this developing story as more information becomes available.
