A 21-year-old man was sentenced to 15 years in state prison Monday after pleading guilty in 171st District Court in the fatal shooting of a 19-year-old man outside a Halloween night party in 2011.

Judge Bonnie Rangel sentenced Jesus Robles, who was convicted of a murder charge in the death of Hector Gonzalez, court records show.

According to court documents, Robles shot and killed Gonzalez during a confrontation between two groups outside a house party in the El Paso Hills area in east El Paso County.

A complaint affidavit stated that Robles fired a handgun after a person in the opposing group had dared him to shoot as the group kept coming forward even after gunshots had been fired into the air.
