Bronx District Attorney’s Office spokeswoman Patrice O’Shaughnessy tells PEOPLE that while 39-year-old Juan Rodriguez has been charged and arraigned in connection with the July 26 deaths of 1-year-olds Luna and Phoenix, the case has not been presented to a grand jury for indictment.

O’Shaughnessy confirms prosecutors have six months to present a case to a grand jury, who could move to indict Rodriguez, an Iraq war veteran.

“We are not presenting to a grand jury at this time,” O’Shaughnessy tells PEOPLE. “We still need to conduct the investigation. We have to make sure that we know all the facts and everything that happened.”

O’Shaughnessy says Rodriguez, who is out on bond, will be back in court on August 27 for a status hearing.
