Attorneys will argue next month if a Manchester man recently found guilty of trying to kill his ex-girlfriend more than a decade ago should be tried yet again. 63 year old Robert Krogmann of Manchester was found guilty of attempted murder and willful injury during a jury trial in August. The trial took place in Black Hawk County after it was moved from Delaware County. Krogmann’s sentencing hearing was moved up a month at the request of attorneys. The hearing will now take place on Monday, October 4 at the Black Hawk County Courthouse. Krogmann was on trial again for the March 13, 2009, shooting of his ex-girlfriend, Jean Smith, who is now 60. During the trial, prosecutors argued that Krogmann intended to kill Smith after she said she did not want to restart their relationship, while Krogmann’s attorneys argued that his mental health diagnoses “impaired his ability to form specific intent” to kill.
