WICHITA, Kan. (AP) — A slain Kansas psychiatrist was stabbed more than 160 times at his clinic in Wichita last month, according to a newly released arrest affidavit for a patient charged in the attack.

Umar Dutt, 21, is jailed on $1 million bond on charges of first-degree murder in Dr. Achutha Reddy’s Sept. 13 killing at his Holistic Psychiatry Services clinic.

A clinic employee reported hearing Reddy calling for help and then seeing Dutt stabbing the psychiatrist, according to the affidavit written by a Wichita police detective. The employee was able to briefly separate the two. Reddy then ran out the back of the clinic with Dutt following him, according to the affidavit, which was released Thursday.

Reddy also suffered “blunt force trauma” and may have been run over by a vehicle, the affidavit states. The doctor who conducted the autopsy on Reddy also identified “approximately 165 sharp force trauma injuries.” Investigators haven’t released a possible motive in the attack.

A short time after the stabbing, a country club security guard spotted a blood-covered man sitting in a car registered to Dutt’s father and called 911. Dutt was taken to a hospital, where medical staff determined he wasn’t physically injured.

Defense attorney Kurt Kerns told The Wichita Eagle that “more evidence will be coming to light” and “everybody is entitled to be presumed innocent.”
