Prosecutors say Debra Haynes-Thomas, 48, got into an argument with Peter Weipert, 56, at his home on Princess Drive in Cheektowaga.
As he was falling asleep, prosecutors say Haynes-Thomas then struck him on the head multiple times with a ceramic statue, killing him.
Later on, police received a tip that led them to Weipert’s home. When they arrived at the building, they began to smell natural gas coming from the house.
Inside, police found every gas stove burner on, along with a lit candle next to the stove on the counter. Police then ventilated the house and performed a security sweep.
Weipert’s body was discovered covered in blankets and pillows in his bed.
Haynes-Thomas was subsequently charged with manslaughter and now faces up to 25 years in prison when she is sentenced in May.
