The eight-member jury was unanimous in its decision handed down in U.S. District Court in Grand Rapids shortly before 3 p.m. today.
Attorneys say today's decision is the final lawsuit over a boating crash that took the life of a Spring Lake High School student and severely injured two other people on Labor Day weekend 2009.
Jurors awarded Alexis Youngberg $4.6 million in damages after finding Jack McKeough negligent. Jurors said Jack's father, Michael McKeough, was also liable in the case because he owned the boat his then-14-year-old son was driving that crashed into a personal watercraft that Youngberg was riding.
The driver of the personal watercraft, Robby Jerovsek, was killed in the crash.
"There are no winners," Sue Jerovsek, Robby's mother, said after the jury's decision today.
Another passenger on the personal watercraft, Kaitlin VanDam, was also injured in the crash. Youngberg lost her leg.
