An Oklahoma man called 911 while allegedly stabbing his father, asking the dispatcher which body part on his father he should attack next.

Erick Nimsey, aged 41, did not resist when officers arrested him on Monday after he called 911 from an apartment complex in Del City, just outside of Oklahoma City. Nimsey faces charges of domestic assault and battery with a deadly weapon, along with domestic assault and battery causing severe injury. According to KWTV, a local CBS station, the alleged victim is his father, 63-year-old Eddie Davis.

The report from KWTV also included details about Nimsey’s 911 call, where he posed a chilling question to the shocked dispatcher: “You want left or right foot? Which one do you want, dispatcher? Whoever you are?” This question was allegedly in reference to which part of Davis he should stab next.

Nimsey reportedly continued to pressure the confused dispatcher, telling her, “Say left or right, and this will be on you.” Davis could be heard speaking in the background and reportedly screaming while his son allegedly continued attacking him.

“If you don’t answer in three seconds,” Nimsey warned, “then I’m going to assume you said ‘left,’ OK?”

The dispatcher responded frantically, “What is happening?”

According to KWTV’s reporting, the dispatcher spent six minutes trying to keep Nimsey talking until officers arrived at the scene. When they did arrive, Nimsey reportedly told the dispatcher that he refused to open the door, and “if you want it open, you can kick it in.”

The officers apparently took Nimsey’s advice and proceeded to kick down the door to the apartment. Inside, body camera footage revealed a bloody scene in the kitchen where Davis lay. Officers located Nimsey in a nearby room, already on his knees with his hands behind his back.

Davis was taken to the hospital with life-threatening injuries.

Police said that after Nimsey was arrested, he made several delusional comments, including a claim that he was 120 years old and that officers were plotting to kill his mother. He reportedly threatened to stab the officers, but also stated that he could get “lions and tigers” to commit the crime for him. KWTV reported that Nimsey asked the police several times, “Do you believe in mercy?”

Nimsey was booked into the Oklahoma County Detention Center on $25,000 bond.
