A Kansas man accused of attacking a prosecutor after a judge upheld his life sentence for a child sex crime will be tried in June on a charge of attempted premeditated murder.

KWBW Radio reports 27-year-old Michael Sherman, of Hutchinson pleaded not guilty to charge at his arraignment Wednesday. A Reno County judge then scheduled his trial for June 10.

Authorities say Sherman lunged at Reno County District Attorney Keith Schroeder in a courtroom last July.

Witnesses said Sherman jumped from his seat, put Schroeder in a headlock and tried to choke him with the chain of his shackles. A judge had just reaffirmed Sherman’s life sentence for sodomizing an infant.

Sherman’s lawyer has said there was no evidence of premeditation or intent to kill Schroeder.
