CLEVELAND, Ohio -- Two men, including the brother of professional wrestler Dolph Ziggler, pleaded guilty Friday in the 2016 killing of a Marine Corps veteran during a botched drug robbery at a Cleveland hotel.

Donald Nemeth, 30, and Jack King, 52, pleaded guilty to involuntary manslaughter, aggravated robbery and kidnapping charges in the Jan. 23, 2016 slaying of Joshua Mascol at the University Hotel and Suites on Euclid Avenue.

Judge Shannon Gallagher will sentence both men Aug. 28 in Cuyahoga County Common Pleas Court. Nemeth was ordered to wear an ankle monitor on home detention until his sentencing.

Nemeth and King were set to stand trial Monday on charges including aggravated murder. Both faced possible sentences of life in prison if convicted.

Cuyahoga County prosecutors had asked the judge to bar Nemeth's lawyers from mentioning his brother Nicholas Nemeth, a two-time WWE World Heavyweight champion known by the ring name Dolph Ziggler, during a trial. The relationship was irrelevant to the case, and bringing it up would draw jurors' focus away from the evidence, Assistant Cuyahoga County Prosecutor Zachary Humphrey argued.

Lawyers for Donald Nemeth and King also asked for separate trials, because they blamed each other in statements to investigators. Defense attorneys argued they could not adequately defend themselves if they were prosecuted together.

Nemeth and King tried to rob Mascol, 34, during a drug deal at the hotel. A scuffle broke out, and Mascol was shot three times in a hallway, prosecutors said.

Hotel surveillance cameras helped investigators identify Nemeth and King, who were arrested and charged several months later.
