Husband of missing pregnant woman admits he killed her during argument

SCHOFIELD BARRACKS, Hawaii (KHON2) — The Army soldier involved in the disappearance of his wife, Mischa Johnson, appeared in a military courtroom for the first time on Tuesday, June 3.

During the hearing, Private First Class Dewayne Johnson, who is charged with his wife’s murder, admitted he killed her during an argument in July 2024.

Nineteen-year-old Mischa Johnson was first reported missing in August 2024, prompting several searches by family and friends. She was six months pregnant at the time of her disappearance.

In Monday’s hearing, PFC Johnson said that on July 12, Mischa accused him of cheating and threatened to keep him out of their baby’s life.

He added that the argument made him “overwhelmed with rage.” He then grabbed a machete he kept next to his bed and struck Mischa in the left temple.

Prosecutors and the defense counsel are working to finalize details of the plea agreement, where PFC Johnson has agreed to voluntary manslaughter instead of murder.

He faces several other charges in connection with Mischa’s death, including obstruction of justice.
