BENSALEM A Bucks County man was charged Tuesday with killing his 59-year-old mother with carbon-monoxide fumes from a portable generator, police said.
Koustantinos Yiambilis, 30, is accused of using the portable generator Monday night to kill Karen Yiambilis at Longmeadow Apartments in the 300 block of Bristol Road, Bensalem police said.
District Attorney David W. Heckler said the son had been warned not to operate the generator inside the apartment, which he shared with his mother.
"We are entirely satisfied he intended his mother's death," Heckler said. "He may have intended his own death."
