MANUEL VASQUEZ, the last of three men arrested in the 1998 slaying of San Antonio drug dealer Juanita Ybarra. Vasquez, now 46, was the only defendant to receive the death penalty. One co-defendant was awarded a seven-year plea deal in exchange for his testimony against Vasquez. The other is serving a 35-year term. Vasquez was originally scheduled to be executed in August, but a paperwork problem led to a delay.
