OAKLAND TWP — A township man is accused of seriously burning his former girlfriend during an altercation at his home on Route 68 earlier this month.

State police Thursday arrested 35-year-old Marshall W. Karenbauer on felony assault and other charges. He is being held in the Butler County Prison on $30,000 bail.

Police said Karenbauer about 1 a.m. July 1 got into an argument with the 12-year-old son of his ex-girlfriend, Mary C. Wetzel, at his house in Oakland Township.

Wetzel was away at the time but when she returned to the home, she found that the defendant had strewn some of her belongings in the yard.

Among the items was a bed pillow, which had been lit on fire, police said.

“When (Wetzel) attempted to retrieve her belongings from the yard,” according to court documents, “the defendant kicked the flaming pillow onto (her) legs, causing severe injuries to the victim’s legs.”

Wetzel was taken to Butler Memorial Hospital and later admitted to the West Penn Hospital burn unit in Pittsburgh.

Her condition was not known this morning; however, police said Wetzel on Wednesday underwent surgery for her burn-related injuries.

District Judge Lewis Stoughton on Thursday arraigned Karenbauer on charges of aggravated assault, simple assault, reckless endangerment, harassment and disorderly conduct.

A preliminary hearing is set for 2 p.m. Tuesday at Stoughton’s office in Chicora.
