CLEVELAND -- A three-judge panel on Monday officially found serial killer George Brinkman guilty in a trio of murders, meaning he can receive the death penalty when he is sentenced next month.

He is scheduled for sentencing Dec. 28.

Brinkman, 45, pleaded guilty to killing a North Royalton woman and her two daughters in June 2017. He's also accused of killing a Canton area couple, whose bodies were found the following day.

Brinkman faced charges of aggravated murder, kidnapping and offenses against a human corpse for the killings of Suzanne Taylor and her daughters, Taylor and Kylie Pifer. Court records say Brinkman cut Taylor's throat, strangled Kylie Pifer with a telephone cord and smothered Taylor Pifer to death. Their bodies were discovered in their home on June 11.

Brinkman was arrested after an eight-hour standoff at his Brunswick home.

Brinkman is also facing murder charges for the deaths of Rogell and Roberta John of Lake Township. Their bodies were discovered on June 12.
