A man who brutally beat his wife to death aboard an Alaska cruise in front of their children has now been found dead in prison.
Officials have yet to release a cause of death but say foul play is not suspected.
Kenneth Manzanares was sentenced to 30 years for the crime and was in custody when he was found unresponsive in his cell Wednesday morning, FOX 8 reported.
In June 2021, Manzanares pleaded guilty to second-degree murder of his wife, Kristy Manzanares.
The Alaska Department of Corrections said life-saving measures were attempted before he was later pronounced dead, according to FOX 8.
The department said Alaska State Troopers and the state medical examiner’s office review the deaths of people in custody.
Authorities say they do not suspect foul play in Manzanares’ death, FOX 8 reported.
Kenneth and Kristy got into an argument aboard the Emerald Princess cruise ship on the night of July 25, 2017, about Kenneth’s behavior. The argument turned physical.
His daughters saw his father continuously pummeling their mother’s face with his fist and went for help.
Before security arrived, Kristy’s brothers and father said they saw Kenneth attempt to drag his wife’s body toward the balcony.
One of her brothers grabbed hold of her ankles and pulled her back into the cabin, but Kristy died from her injuries.
In the court filing, Kenneth Manzanares' lawyer asserted he suffered from brain abnormalities consistent with injuries playing contact sports.
In addition, his defense stated Kenneth Manzanares suffered from undiagnosed bipolar disorder, and when combined with alcohol and prescribed medication, his mental state caused the violent episode that killed Kristy.
