Tomah homicide suspects bound over for trial

A Monroe County judge found enough evidence to bind over two suspects for trial who are charged in the stabbing death of a 43-year-old man in a Tomah hotel.

Zachary Davis, 26, and Sebastian (AKA Sabrina) Martinez, 20, appeared in person in Monroe County Court for the first time on Friday. During their bond hearing, they appeared via video conference.

Davis and Martinez have been charged in the death of Derek Magnuson. An autopsy determined Magnuson died of multiple stab wounds from a large knife or similar instrument. He was found in a room at the EconoLodge Hotel on the night of March 11.

A Tomah Police investigator testified Friday about what he saw when he entered the hotel room. “He was on the floor just within the door of room 118. There was broken glass on the floor, blood on the walls and on the floor,” said Investigator Rob Walenski.

According to the criminal complaint, Martinez told investigators Magnuson tried to grab him and Davis got upset. Magnuson and Davis began to fight. Martinez stated Davis pulled out “the knife” and stabbed Magnuson multiple times and he and Martinez left the hotel after Davis took Magnuson’s wallet.

They were arrested in Tennessee on March 22.
