An uncle and nephew have admitted they tried to kill off witnesses to clean up loose ends in another murder case.

Powe was found dead near 12th and vine in July of 2015.

The 17-year-old Eskridge, a witness to that killing, was also killed.

Smith and his nephew, Shaheem Smith, then pleaded guilty to conspiracy to commit murder.

They admitted that they tried to kill another witness to Powe's death.

Shaheem Smith will be sentenced April 6.

Antonio Smith's sentencing is April 28.
