According to an official notice from the Court of Criminal Appeals of Texas, John Henry Ramirez's execution date for Oct. 5 will stand.
There was no further information available as to why the motion for a stay of execution was denied.
Back in June, 94th District Court Judge Bobby Galvan ruled against Nueces County District Attorney Mark A. Gonzalez's motion to withdraw the Oct. 5 execution date, to which Gonzalez said he would appeal.
Ramirez was convicted of killing convenience store clerk Pablo Castro in 2004.
The court denied the motion for a stay of execution without a written order.
