While the circumstances surrounding the scene ruled it a homicide, there were no visible wounds and x-ray results did not reveal a cause. The coroner says findings in the temporal bone, which are located at the sides and the base of the skull may indicate a drowning, but there is not enough evidence to prove it.

The prosecution came to rest on the fourth day of the trial for Gabriel Salyers. The state called to the stand the lead detective in the case, Sean Niemeyer, as well as Lucas County Coroner, Dr. Diane Scala-Barnett, who performed the autopsy of infant Jaxxon Sullivan. The jury saw visuals such as an interview with Sullivan's mother, Shelly Wireman, who told police her and Salyers had been using suboxone.
