SAGINAW, MI — A jury has again convicted Stephon L. Roby of killing his mother and 11-year-old sister in 2013, returning guilty verdicts after roughly two hours of deliberations.

Jurors found Roby guilty of two counts of first-degree premeditated murder and four firearms-related felonies on Sept. 25, according to MLive’s report from the retrial. He faces two terms of life without parole. An appellate court had overturned the convictions for which he was previously serving that punishment.

The victims were Leigh A. King, who had just celebrated her 42nd birthday, and her daughter, Sharleea A. King. Prosecutors John K. Kauten and Brooke N. Kozlowski argued that Roby shot both repeatedly in the head with a .22-caliber rifle early on March 6, 2013.

About 1 p.m., Roby called 911 and reported finding their bodies in his mother’s bedroom at 208 Hess St. He claimed someone had broken into the home and killed them.

When the verdicts were announced around 4:30 p.m., relatives embraced and quietly cried. Roby showed no visible emotion. Defense attorney Alan A. Crawford declined comment.

Chief Assistant Prosecutor Blair N. Stevenson said the years between trials complicated the prosecution: some witnesses had died, illness prevented others from testifying, and another traveled from outside Michigan. The appellate ruling also barred evidence used previously. Stevenson credited months of preparation by Kauten and Kozlowski and said prosecutors strengthened portions of their case for the retrial.

Presumption of Innocence: A presumption of innocence means that any defendant in a criminal trial is presumed to be innocent until they have been proven guilty beyond a reasonable doubt in a court of law. The defendant in this case is only accused of the charges set forth in the criminal complaint. They are innocent until proven guilty.
