Son 'disappointed' he didn't kill mother with box cutter

A 21-year-old man was "disappointed'' he didn't kill his mother when he used a box cutter to slice her neck, then spit on her after she fell in front of the Larimer County Courthouse Offices building, investigators wrote in court documents released Wednesday.

Michael Contreras was arrested on suspicion of attempted first-degree murder and first-degree assault Tuesday afternoon in front of the building at 200 W. Oak St., near Old Town. During an interview with investigators, Contreras told police he had been contemplating killing his mother for a couple of days, an officer wrote in an arrest affidavit.

The officer told Contreras that his mother was going to survive her wound. He replied, "Damn it. That's disappointing."

Formal charges in the case are pending, and bond has been set at $1 million. The man is next due in court Tuesday.

Contreras’ mother was treated and transported to Medical Center of the Rockies in Loveland with serious bodily injury. She was no longer listed as a patient on Wednesday, and reports via social media indicate she has returned home.
