A north Mississippi woman has surrendered to police, saying she shot and killed her husband.

Hernando police say 34-year-old Jamie Lynn Johnson turned herself in Wednesday night, saying she’d killed her husband hours earlier. The man, Gregory Johnson, was found dead from a single gunshot wound in a bedroom.

Hernando Police Chief Scott Worsham tells WMC-TV the couple had a history of domestic violence.

Johnson is charged with murder, with a judge setting bail at $250,000. Bail was revoked on previous child neglect charges, though.

Worsham says the couple was reported for locking their three children in the house by fastening exterior doors with zip ties. The state took the children into custody two months ago.

Johnson remains jailed Friday in DeSoto County. It’s unclear if she has a lawyer.
