COUNCIL BLUFFS, Iowa (AP) — A competency hearing and murder trial for a 30-year-old man charged with killing his mother and grandmother in Council Bluffs have been delayed. The Daily Nonpareil reports a hearing to determine whether Michael Dieckmann is mentally fit to stand trial was set for Monday but a prosecutor and defense attorney asked for more time. They say doctors are still evaluating Dieckmann.

He is charged with two counts of first-degree murder in the March deaths of his mother, 63-year-old Jacqueline Dieckmann, and his grandmother, 91-year-old Illa Pfeiffer. The competency hearing is now set for June 27. Dieckmann’s murder trial was originally scheduled to begin June 1, but will now be held Aug. 23.

Dieckmann remains in the Pottawattamie County Jail on $1 million bail.
