Brianna Alvelo, 22, is charged with attempted murder, home invasion with a firearm, kidnapping and aggravated assault, according to court records.
Alvelo delivered the pizza, which cost about $33, and was asked to give change for a $50 bill, the affidavit said.
But Alvelo did not have change, and the woman searched for smaller bills, giving Alvelo only a $2 tip in the end, authorities said.
The woman said that sometime later, she heard a loud knocking on the door, the affidavit said.
A man and a woman clad in all black wearing masks forced themselves into the room when she opened the door, it said.
But Alvelo grabbed the phone, smashed it, and "began striking her multiple times with the knife," according to the affidavit.
The woman was stabbed 14 times, with wounds to her chest, arms, legs and abdomen. »
