An Arkansas woman has vanished after she was accused of murdering her husband and released on bond.

Dawn Rene Wynn, 49, is accused of murder and armed criminal action in connection to the 2021 shooting death of her husband.

"She should be considered dangerous and could be armed," the McDonald County Sheriff's Office in Missouri said in a statement posted to Facebook. "She is accused of, and charged with shooting her husband in the back of the head while he slept." 

Wynn was "under court monitoring" when she was released on bond, at which point she only had to check in with authorities via telephone before she went missing, the sheriff's office told Fox News Digital.

The McDonald County Sheriff's Office said Wynn was released as a result of a 2019 Missouri Supreme Court ruling on a Missouri Bond Reform law, which allows certain Missouri criminals out on bond in an effort to make the criminal justice more fair to those who cannot afford bail.
