ELLSWORTH, Wis. -- (KTVI/AP) -- Miguel Navarro, 24, was charged Thursday with first-degree intentional homicide and mayhem in the death of 37-year-old Israel Valles-Flores.
According to the criminal complaint, Navarro was seen attacking Valles-Flores with a circular saw while on a home's roof near River Falls, Wisconsin. A witness said Valles-Flores handed the saw to Navarro, who immediately cut into the victim's neck. A bloody circular saw was found on the ground.
During a recorded jail call, Navarro said the other workers, including Valles-Flores, were teasing him because he wasn't feeling well.
