A landlord surnamed Yang stood trial at Shunyi district court Tuesday on suspicion of negligent homicide, the Legal Mirror reported.
The 18-year-old victim, surnamed Zhang, was a student intern and rented Yang's house in October last year. Yang painted the house on December 28, 31 and January 3. Due to the cold weather, he lit a stove but carbon monoxide leaked into Zhang's room, poisoning him.
