BOULDER — A Boulder County jury convicted a Longmont man of first- and third-degree assault in a September 2012 incident in which he was accused of slashing an acquaintance with a knife after he was asked to clean his own vomit out of a rented limo.

According to police, Saul Ayala spent the evening with a group of people in Denver, but vomited in a limo on the ride home.

Witnesses told police that two occupants were dropped off in Del Camino, then the limo left for the Ayala’s home in Longmont to drop him off. Two women got out of the limo to let Ayala out, and he got angry at them because they asked him to help clean up his vomit and to pay for the damage caused to the rental. Other witnesses told police that Ayala walked into his home and returned with both a knife and a handgun.

They told police that Ayala poked one of the women in the face with a sharp object largely concealed by his hand and struck both of them in the face. A man stepped out of the limo and told Ayala to back off from the women, according to the police report. The man reported to police that Ayala grabbed him by the neck and pulled him forward hard. At that point, he told police, he felt his face “rip” open.
