ST. LOUIS • The state's highest court Tuesday denied the St. Louis Circuit Attorney's Office appeal to block a grand jury search warrant as part of a perjury probe of the man hired to investigate former Gov. Eric Greitens last year.

On Tuesday, Kimberly M. Gardner, St. Louis' elected prosecutor, sought the Missouri Supreme Court's ruling on whether a St. Louis circuit judge had the authority to issue a search warrant for electronic data on the Circuit Attorney's Office's servers.

The high court's ruling allows a grand jury's Feb. 21 search warrant for six months of emails, attachments and other electronic data to be executed. It was not immediately clear how quickly police and a special prosecutor would seek to carry out the search warrant.
