WICHITA, Kan. (AP) — Court records show a slain Kansas psychiatrist was stabbed about 165 times outside his clinic in Wichita last month.

The arrest affidavit for the suspect, 21-year-old Umar Dutt, was released Thursday. He’s charged with first-degree murder in the Sept. 13 death of Achutha Reddy at his Holistic Psychiatry Services clinic.

The affidavit says a clinic employee reported hearing Reddy calling for help and then seeing Dutt stabbing the psychiatrist. The employee was able to briefly separate the two.

The affidavit says Reddy also suffered “blunt force trauma” and may have been run over by a vehicle.

Dutt was a patient of Reddy’s. Investigators haven’t released a possible motive.

Dutt is jailed on a $1 million bond. His attorney tells The Wichita Eagle “more evidence will be coming to light.”
