The police said the attack happened early Monday in the beach town of Rincon. They said the assailant broke into the Arena y Mar Apartments through a sliding glass door in the middle of the night.
Brett Walquist apparently walked in on him in the kitchen and was stabbed at least three times. Walquist lived in Beavercreek, Ohio.
Walquist grew up in Michigan and was a graduate of Byron Center High School. His brother operates the family-owned Alger Bikes in Grand Rapids and said Walquist used to work there.
So far, no arrests are reported.
