A 39-year-old mother from Colorado City, Texas was found dead inside her car two days after she was reported missing, local media reported Monday.

Amber Sevier's car was halfway submerged in a ravine southwest of Abilene, the Mitchell County Sheriff's Office told KWES. Investigators said it was unclear how her car ended up in the water.

Sevier had called a friend on Saturday night before her phone either died or was turned off, sheriff Patrick Toombs told KTXS.

Invesigators said they planned to conduct an autopsy.
