A 300-pound woman has pleaded guilty to killing her 120-pound boyfriend by sitting on him

A 300-lb Pennsylvania woman who killed her boyfriend by hitting him with a table leg, then sitting on him has pleaded guilty to third degree murder. Windi Thomas allegedly told police she had been drinking and craving crack cocaine when she smothered 120-lb. Keeno Butler during an altercation in March.

The cause of death was “respiratory insufficiency secondary to blunt force trauma to the neck and thoracic compression, exacerbated by blunt force trauma to the head,” according to Goerie.com.

Thomas will be in court Dec. 21 for sentencing. Prosecutors are recommending the woman spend 18 to 36 years behind bars. Both Thomas and Butler were 44 at the time of the incident. Had Thomas been found guilty by a jury, she could have been incarcerated for 40 years.

“It’s a good result based upon the facts of the case,” Thomas’ court-appointed lawyer, Mark Del Duca told reporters. “I think it’s fair for both sides.”

The victim’s sister, Sandra Butler, thought Thomas’ got a light sentence for killing her brother.

“She deserved life,” Butler said.

Police investigators said that Thomas also slashed Butler across his hand with a knife before sitting on him, with her head pressing against the sofa for leverage. After the murder, Butler reportedly called 911 and confessed that she killed someone.
