HUTCHINSON, Kan. (AP) — A Kansas man has been convicted of attempted first-degree murder for a courtroom attack on a county prosecutor.

The Hutchinson News reports a Reno County jury deliberated nearly six hours Wednesday before returning the verdict against Michael Sherman.

The attack last July 10 left Reno County district attorney Keith Schroeder with red marks on his throat from Sherman’s wrist and belly chains.

Sherman leaped on Schroeder just after a judge had reaffirmed his life sentence for sodomizing a 4-month-old baby. The attempted first-degree murder charge alleged the attack was premeditated.

Sherman’s life sentence for criminal sodomy of a child was later reduced to 13 years and nine months in prison. But he now also faces about 20 years for the new conviction.
