(CNN) -- "I killed that lady," the 10-year-old boy told a Pennsylvania state trooper, after a 90-year-old woman was found dead in the home of the boy's grandfather.

Tristen Kurilla, a fifth grader, made the chilling confession Saturday, police said, after his mother brought him to the Pennsylvania State Police Barracks in Honesdale, about 140 miles north of Philadelphia.

Now, Kurilla is being held at the Wayne County Correctional Facility and charged as an adult with criminal homicide, the Wayne County district attorney's office said. The boy is separated from adult offenders and is being constantly supervised, CNN affiliate WBRE reported.

The boy admitted to grabbing a wooden cane, holding it against 90-year-old Helen Novak's throat for several seconds and punching her in the throat and stomach, according to the police affidavit.

Kurilla told police he was angry at Novak because she had yelled at him when he entered her room. He said he wanted to ask her a question.

Were you trying to kill her? the trooper asked the boy.

"No, I was only trying to hurt her," Kurilla replied, according to the affidavit.

The boy was ordered to be held without bail after his arraignment and is set to appear in court October 22.

Bernie Brown, his lawyer, said he was petitioning the court to get the fifth-grade Damascus Elementary School student out of jail, WBRE reported.

"Tristen really kind of doesn't have an idea of what is going on," Brown told the station.

Brown added, "Jail is still jail, no matter what part of the facility you are in."
