Dwayne Smith punched Clifford Thomas, the killer of his 3-year-old daughter, in the back of the head during his sentencing in a Detroit courtroom. The grieving father hit Thomas while he was giving a victim impact statement.

Jasmine Gordon, the child’s mother, and her boyfriend, Clifford Thomas, were found guilty of manslaughter after Jamila Smith died of multiple blunt force trauma injuries in September of last year.

Gordon was sentenced to seven to 15 years for involuntary manslaughter and 14 to 25 years for first-degree child abuse, to be served concurrently. Thomas was sentenced to six to 15 years for involuntary manslaughter.

Smith was removed from the courtroom, but he was not charged.
