SPARTA, Wis. (WKBT) -

The man accused of killing another man in a Tomah motel will spend the rest of his life behind bars.

A judge sentenced Zachary Davis to life in prison Thursday with no chance of extended supervision. A jury convicted Davis in the stabbing death of 43-year-old Derek Magnuson at a Tomah motel in March of last year.

Prosecutors say Davis and his significant other, Sebastian Martinez, killed Magnuson in a hotel room the three were sharing. They were eventually arrested in Tennessee.
