WAUKESHA COUNTY, Wis. (CBS 58) -- A Menomonee Falls man was sentenced on Thursday, April 10, after he "blacked out" while driving due to his epilepsy, which killed two people last year.

Fifty-year-old Jade Moen was sentenced to 25 years in prison. 

The crash happened near Pewaukee Rd. and Capitol Drive. Moen said he was heading west when he blacked out. 

Police said he first rear-ended a sedan, killing a 76-year-old woman behind the wheel, before his truck continued west into a construction zone. Witnesses estimated Moen's speed was about 30 miles per hour when he hit the sedan but went up to between 60 to 80 miles per hour when he entered an area blocked off by orange cones. A 46-year-old construction worker was then killed, and another worker was injured and taken to a local hospital.

Investigators said when Moen later woke up, he handed over two forms of identification -- one of which was marked "VOID" and the other which had "Not a Driver's License" written on it in red.

Driving records show his license was "surrendered indefinitely."

Moen said he had suffered from seizures since 2010 and takes medication for it twice a day. His wife later told investigators that despite the treatment, her husband has "breakthrough seizures" and that he's had them while driving in the past.

Cord records show Moen plead not guilty in August.
