The Indiana Supreme Court is expected to hear an appeal case Thursday from Desmond Turner, the convicted triggerman in the Hamilton Avenue murders. Turner was convicted in November 2009 of killing four adults and three children during a home invasion and robbery in Indianapolis—the worst mass murder in the city's history. He waived his right to a jury trial to avoid the death penalty. A judge sentenced him to life in prison without parole. Turner argues the judge was wrong in admitting certain evidence and that there was insufficient evidence to sustain the convictions.
