DETROIT -

Two adults convicted in the death of a 4-year-old Detroit boy who was accidentally shot by his 4-year-old cousin didn't show up for sentencing on Wednesday.

After more than an hour and a half of waiting, judge Qiana Lillard issued arrest warrants for Patricia Johnson and Harvey Witcher.

The two were supposed to be sentenced on involuntary manslaughter charges after taking plea deals last month.

Lillard also revoked their bonds.

Police said Jamel Witcher Jr. was accidentally shot by his cousin in a home on Tuxedo Street in January. The gun belonged to the boy's grandfather, Harvey Witcher. He, Johnson and a third adult, Robert Richardson were in the home at the time of the shooting and subsequently charged.

Another sentencing hearing has been scheduled for Friday.
