A Black Hawk County jury has convicted a Waterloo man on two counts of first-degree murder. The jury rendered the verdict against Martaves Keys Thursday morning, finding the Waterloo man guilty of both murder counts in the November 2007 shooting deaths of Ronald Scullark Junior and Anissa Schroeder.

The jury got the case Wednesday afternoon and deliberated for about three hours. Jurors returned to the courthouse to resume deliberations Thursday morning and presented their verdict around 10:30 A.M. During the trial, which lasted nearly three weeks, prosecutors accused Keys of killing Scullark and Schroeder while trying to steal drugs.

The victims were both shot in the head from close range in an S-U-V that crashed into a fence in front of a Waterloo home. The verdict means Keys will spend the rest of his life in prison with no possibility for parole.
