Prosecutors are seeking additional charges against the Cleveland man accused of keeping three women captive in his home for a decade , they told a judge . At a eight-minute hearing Wednesday , Ariel Castro , 52 , kept his head down , often closing his eyes and speaking only to answer `` yes '' or `` no '' to the judge 's questions . Prosecutor Timothy McGinty told Cuyahoga County Judge Michael Russo there is a possibility of more charges . `` We are presenting additional evidence to the grand jury next week and the week after . We expect we are going to request further indictments , '' he said . Castro faces 329 counts , including one count of aggravated murder for allegedly causing the unlawful termination of a pregnancy . Castro 's lawyers have filed a speedy-trial motion , which would mean the case would have to be tried by August 4 . However , that deadline could change if Castro 's attorneys change course and ask for more time to prepare for the case . Russo set the next pretrial hearing for June 26 and told the prosecution and defense that any plea deal would need to be in writing . The defense has said in the past that it would be open to a plea deal if the death penalty was taken off the table . This week , Castro entered a not guilty plea to all charges , including 139 counts of rape and 177 counts of kidnapping Michelle Knight , Amanda Berry and Georgina `` Gina '' DeJesus . Castro fathered a daughter with Berry , according to authorities . Police have alleged Knight was impregnated by Castro five times , but he would punch her in the stomach , resulting in miscarriages and termination of all the pregnancies . Authorities said last week they are conducting DNA tests on evidence to determine if additional victims were inside Castro 's Cleveland home , and the state attorney general 's office says the crime lab is reviewing additional evidence in the case . Since the case began , investigators have been looking for evidence of aborted fetuses and evidence of any other girls or women who may have been kidnapped or held captive in the house .
Prosecutors say they are seeking more charges against Ariel Castro . A grand jury will hear additional evidence next week . The defense has asked for a speedy trial , which would mean the trial would start by August 4 . Castro did n't say much during short hearing .
