A woman has pleaded guilty to killing her boyfriend by stabbing him, hitting him with a table leg and crushing him under the weight of her roughly 300 pounds.

Windi Thomas, of Erie, faces a sentence of 18 to 36 years after pleading guilty to third-degree murder. She had been scheduled for trial next week, but instead will be sentenced on Dec. 21.

The 44-year-old Thomas admitted killing Keeno Butler last March, partially by lying on top of him. Thomas weighs about 300 pounds, while the 44-year-old Butler weighed about 120 pounds.

Thomas was reportedly drunk and wanted to smoke crack when the pair got into an argument that ended in Butler's death.

Butler, who went by the nickname "Loco", is survived by a daughter, Adele Brown, two grandchildren, his mother and nine siblings including Sandra, according to his obituary.
