Boulder District prosecutors on Thursday charged a 20-year-old Frederick man accused of stabbing three men at a Longmont party on Sunday with two counts of first-degree murder, one count of attempted first-degree murder and one count of first-degree assault.

Secundino "Dino" Martinez started to speak in Boulder District Court on Thursday morning, but was only able to say "Your Honor" before public defender Eric Zale intervened and quickly approached him and said, "Zip, zip, zip." About 20 people attended the brief morning hearing to support Martinez, who appeared in orange and white striped jail scrubs, handcuffs and shackles.

His eyes appeared bloodshot as he watched the charging hearing.

Martinez was arrested Sunday morning at the Walmart store in east Longmont, where he was waiting for his uncle to pick him up, according to police reports. A detective reported he had blood on his pants and was carrying a bloody shirt.

Police believe he stabbed three people with a kitchen knife at a party on 712 Francis St. after an argument escalated into a fight. Police who responded to 911 calls found 19-year-old Brian Farmer dead of his wounds in the yard of the home. Jerrad Wallace, 18, and Trevor Dolifka, 18, both suffered multiple stab wounds and were taken to Longmont United Hospital for surgery. Wallace succumbed to his injuries and died on Tuesday after he was removed from life support. Dolifka, whose lungs reportedly collapsed while he was still in the emergency room, survived and was listed in fair condition on Wednesday.

When police caught up with Martinez, who reportedly fled the scene first on foot and then using a stolen mountain bike, he told a detective that six people were beating him up so he defended himself, according to his arrest report.

A candlelight vigil is scheduled in Lafayette's Waneka Park at 6:30 p.m. Thursday to remember Farmer and Wallace and to support Dolifka, according to a public invitation posted on Facebook.

Martinez is due to return to court March 4 for a proof-evident hearing. Attorneys initially scheduled it for March 6, but adjusted the date after Martinez's appearance concluded. He is being held at the Boulder County Jail without bond.
