A Mequon man on March 22 was found guilty on four felony charges in the homicide and disappearance of a Kenosha man.

A jury found Zachariah Anderson guilty in Kenosha County Circuit Court of first-degree intentional homicide, hiding a corpse and two counts of repeat stalking.

Anderson's ex-girlfriend had been a relationship with the victim, Rosalio Gutierrez Jr, who went missing on May 17, 2020. The jury trial started Feb. 28.

Anderson is due back in court May 16 for a sentencing hearing. The homicide charge alone carries a mandatory life sentence.

According to the criminal complaint:

Gutierrez's girlfriend reported to police that she had not seen or heard from him since May 17, 2020 and told investigators when she drove to his apartment to check on him no one answered the door and she saw large amounts of blood on the floor and furniture. She contacted police to conduct a welfare check, during which officers discovered blood scattered throughout the main living space and signs of an apparent struggle.

Blood samples taken from the crime scene belonged to Gutierrez, and evidence suggested that he was killed in his home on May 17, 2020 between 9:06p.m. and 9:37p.m.

Gutierrez has not been located or heard from since May 2020 when a friend received a text from him. His credit cards had not been used, and he had not had contact with his two children whom he saw every weekend and normally contacted throughout the week. No other family member, friend or co-worker reported seeing hearing from after he disappeared.

Anderson's ex-girlfriend said she had concerns about Anderson tracking her because he was jealous of her new relationship.

Anderson's laptop revealed that there was folder entitled "Rosalio Gutierrez Jr" that contained photos of Gutierrez, screenshots of information about him from online court records, photos of his business information, electronic maps of his residence and home address.

When officers arrived on May 19, 2020 on Anderson's property, they discovered a smoldering burn pit. The next day, they conducted a search of the pit with a cadaver dog and found remnants of clothing, a charred bleach bottle and steel-toed boots.

A search of second burn pit at Anderson's property in Saukville also turned up remnants of clothing and other fabric that matched the color and fabric of a shirt frequently worn by Anderson.

Investigators also discovered surveillance footage of Anderson, on May 18, 2020, at Wal-Mart in Saukville where he purchased three cans of sardines, two packages of Hefty 13 gallon garbage bags, 2 boxes of latex gloves and two containers of Clorox bleach wipes.
