Some were consuming marijuana and alcohol. The parents of the youth hosting the party were out of state.

"There were about 20 kids in the house," said Longmont police spokesman Jeff Satur. "They were smoking marijuana, drinking."

As the party progressed, police say an argument broke out and moved outside. Several of the victims began fighting and three teens were stabbed.

"(The) disturbance moved outside and a fight broke out and our suspect started stabbing people," Satur said.

Two victims aged 17 and 18 were transported to the Longmont United Hospital. The third victim aged 19 died at the scene.

The two victims at the hospital are in serious condition. All three victims are from Lafayette.

Police arrested 20-year-old suspect Secudino Martinez at a Walmart at around 3:48 a.m. after he allegedly fled the scene on foot. He is currently being held at Boulder County Jail on one count of first-degree murder and two counts of attempted first-degree murder. A court hearing originally set for Monday afternoon has been delayed until Tuesday morning.

"Loud-mouth kid. I assume he was going to get beat up and panicked," said Tyler Stone, who knows Martinez. "The kid just found himself by himself because nobody wants to back up somebody who starts problems for no reason."

Police used dogs to try to find the knife used in the crime. Witnesses described the blade as being three to six inches long. Anyone who locates a knife in the area is asked to contact Longmont police.

"It's just a tragedy. I don't even know what to say about it. A house party gone wrong. And it's just really sad and scary that this happened in such a quiet little neighborhood," neighbor Jordan Storms said.

Authorities have not released the names of the victims.
