MILWAUKEE – A Milwaukee landlord accuses a former tenant of trashing his rental property. It’s a claim he made after two young children were poisoned in his house. When Christopher Knight bought the house at 3046 N. 2nd Street in July 2021, he now admits it had problems. What condition it was in when he rented it out two months later is a point of contention. But it’s clear how the city found it 11 months later.
