GLENWOOD SPRINGS — A 53-year-old Carbondale man pleaded not guilty in Garfield District Court last week to multiple charges of child sex assault stemming from a Carbondale Police Department investigation this spring.

Gustavo Flores Rosario, who remains in the Garfield County Jail on $25,000 bond, in addition to an immigration hold, entered the plea on June 13. A five-day trial is scheduled to begin Nov. 4.

Rosario was arrested May 22 after a month-long investigation that was prompted when an 18-year-old woman reported to police that she had been sexually assaulted by Rosario “several years ago.”

The woman also reported at the time that she was concerned that a 13-year-old acquaintance of hers had been sexually assaulted by the same person, according to a statement from Carbondale Police at the time of Rosario’s arrest.

Rosario was arrested on charges of sexual assault on a child, a class four felony carrying a presumptive penalty of up to six years in prison, or 12 years if “exceptional circumstances” are proved.

Police also said at the time that there may be other victims of sexual assault by Rosario. Carbondale Police Chief Gene Schilling said the alleged assaults took place in Carbondale.

$1 million bond

Also in court on June 13 was Shawn Martin Angell, 43, of Parachute, who faces charges of first degree sexual assault and multiple other felony charges. Angell was arrested by Garfield County Sheriff’s deputies on March 24 following a report of a kidnapping and sexual assault that had occurred outside of Parachute.

Angell remains in the Garfield County Jail on $1 million bond. In addition to first degree sexual assault and second degree kidnapping, he faces charges of trespassing, tampering with evidence, third degree assault, child abuse, illegal use of a stun gun, and first degree burglary.

A July 19 preliminary hearing has been scheduled to determine if enough evidence exists to proceed to trial in the case or accept a plea.
