Ariel Castro's lawyer Craig Weintraub made a brief statement after his client entered a plea of not guilty saying it was the first step in the legal process.
"Although certain charges in the indictment cannot be disputed a not-guilty plea [..] requires the prosecutor continue to evaluate the case to determine whether [...] evidence can actually support an aggravated murder conviction for the death of a foetus and whether the death penalty is warranted."
A pretrial hearing was set for June 19.
