Jury selection in a double-murder trial is scheduled to begin today in Waterloo. The trial of Martaves Keys is expected to last three weeks in Black Hawk County District Court. The 26-year-old Waterloo man is accused of fatally shooting Ronald Scullark Junior and Anissa Schroeder in an S.U.V. in 2007.

Their bodies were found after the vehicle crashed into a fence outside a Waterloo home. Investigators says Keys was riding in the S.U.V.’s back seat when each of the victims was shot in the head. Court records indicate that Keys was seen running from the area holding a gun with blood on his clothing.

Court officials plan to choose a jury from a larger-than-normal pool. The process is expected to take up to two days to complete. Keys has pleaded not guilty to the two first-degree murder charges.
