Editor's note: An earlier version of this story reported that the 17-year-old Lafayette boy had died. The Times-Call has since learned that he is still on life support as of 10 p.m. Monday.

A 17-year-old Lafayette boy stabbed during a fight at a Longmont home Sunday remains on life support, according to a source close to the investigation.

However, his family has reported that he died Monday.

Ashley Wallace, reported on social media as Jerrad Wallace's sister, posted on her Facebook page on Monday, "Jarrad Wallace. Born 1995. Died 2014. May he be watching over us all and sends (sic) his love from above."

Six hours earlier, she posted that he had made it through the night, and was still being strong.

"They will be doing a brain activity test to see if he is ... with us or not," she wrote. She later added that her family needs as much support as possible.

The source confirmed Wallace's identity to the Times-Call.

Neither police nor the Boulder County Coroner's office has released the identities of the other victims stabbed during a party at 712 Francis St. A 19-year-old Lafayette man died at the scene; an 18-year-old man is still hospitalized with serious injuries.

Police responded to the house at 2:07 a.m. after party guests called 911 to report the stabbings.

"People got stabbed I need you to come right now. It was an altercation between friends," the first caller said. "Three of my friends. It got out of hand. I was friends with both of them and they were just being stupid and we got into an altercation."

While the dispatcher was on the line with the first caller, a second man called and reported an emergency to the same address. When a third caller reached 911, the dispatcher asked her if she was calling about the stabbings and assured her help was on the way.

A woman who identified herself as the aunt of the 19-year-old deceased man reported on both Twitter and Facebook that her nephew suffered stab wounds to the face; police told her sister-in-law that the victim was unrecognizable after the attacks. An official close to the investigation confirmed the wounds.

The Boulder County coroner will determine the causes and manners of the deaths.

Police arrested on Sunday Secundino "Dino" Martinez, 20, of Frederick on suspicion of first-degree murder and two counts of attempted first-degree murder.

Investigators reported that an 18-year-old man who lived at the Francis Street home hosted a party with about 20 guests ages 16 through 21. The fray spilled onto the lawn and the victims were stabbed, according to police.

Officers did not immediately recover a weapon and continued a search on Monday afternoon. After a resident summoned police to her home at 730 Francis St., officers recovered a knife from the backyard. Sgt. Joel Post said it will be tested to determine if it was used in the stabbings.
