Neokalus is an adult Caucasian male with short black hair. A towering hulk of a man, he is clad in a red boiler suit (or possibly a dark orange jumpsuit, implying it's his inmate uniform), wears black gloves and grey shoes, dons an undersized pink clown mask, and uses a kitchen knife to kill people. According to a radio report, he's 38 years old, approximately 6'4" (193 cm) tall, and weighs 240 lbs (108 kg). Neokalus Burr was a serial home invader, with a long rap sheet of hot-prowl burglary and an uncharacteristic violence against occupants, as well as an extensive record for mental illness, dating back as early as age 16. Declared criminally insane, he was locked away in a sanitarium for a permanent stay. He escaped out from it in 2025.
