A 15-year-old Wisconsin boy has been charged with attempted first-degree intentional homicide for allegedly punching and choking his mother as she tried to order him a pizza.

Police in the village of Eagle in Waukesha County were called to the home of Andrew Romagna last month after a frantic 911 call reporting that the teen was attacking his mom, WITI-TV reports.

While officers responding to the call were advised to at least pair up to handle Romagna, who was previously known to police, the first officer who arrived at the home heard screaming and charged inside.

Romagna’s mother said he had been angry with his parents for making him lose weight, so she wanted to “make him happy by ordering a pizza,” court documents state.

The teen began attacking her while she was placing the order online. He allegedly punched her “about six times with a closed fist” and then started to choke her, the criminal complaint states.

The mother told officers the assault lasted for roughly 15 minutes.

After police were able to detain Romagna, he reportedly started making numerous statements without being questioned:

“I wanted to kill her,” he said, according to police. “Why is she not dead? I was choking her for so long.”

He reportedly continued: “I was going in for the kill and was going to choke her out and couldn’t choke her out [and] kill her because you came in.”

When an officer tried to switch the subject to football, police say Romagna said he “didn’t understand how, if he was choking her and she was bleeding, that she didn’t die,” the complaint states.

Romagna disclosed to officers he has been diagnosed with paranoid schizophrenia, a condition he has had since seventh grade. He said he doesn’t want to take his medication or undergo therapy any longer.

He also has been diagnosed with depression, the mother told police.

The teen’s defense lawyer has requested a competency hearing, which is scheduled for late October.

Bail has been set at $100,000.
