Care home resident dons 'demonic mask,' stabs staffer more than 30 times, authorities say

A developmentally disabled man allegedly put on a “demonic mask,” played the theme song from the horror film “Halloween” on his iPod, and stabbed his caretaker more than 30 times with a kitchen knife in a group home near Chicago on Saturday, authorities said.

Ederaldo Frantz, 24, was allegedly upset that the 50-year-old woman confiscated his cell phone after he used it to inappropriately contact a female, police said. He now faces two counts of aggravated battery, two counts of aggravated domestic battery and one count of attempted murder.

“It’s straight out of a horror movie,” Will County Sheriff Deputy Chief Dan Jungles told the Chicago Tribune. He described how Frantz allegedly stabbed the woman about six times, then continued to attack her outside after she fled the building.

The blade of the knife broke off during the attack and got stuck in the woman’s chest, police said in a statement. The woman underwent surgery and is expected to recover.

Will County Judge David Carlson approved a request for a fitness evaluation Wednesday. Frantz will be evaluated to see if he understands the charges against him enough to withstand trial.
