Street and Maloney were previously each charged with two counts of first-degree murder, attempted first-degree murder, home invasion, conspiracy to commit first-degree murder and aggravated discharge of a firearm.

Street, Maloney and two other teenagers are accused of engaging in a murder-for-hire plot that resulted in the death of Rebecca Bolin, 52, and serious injuries to her husband Douglas Bolin.
