Police Looking For Knife After Stabbing In Longmont

LONGMONT, Colo. (CBS4) – Police are still searching for the murder weapon after a stabbing in Longmont that killed one teenage boy and put two others in the hospital on Sunday.

Authorities say the stabbing happened during a party at the home of an 18-year-old boy whose parents were out of town.

"One kid is dead now, two others struggling for their lives," said Longmont Police Commander Jeff Satur.

Longmont police say about 20 young people aged 16 through 21 were at the party when a fight broke out.

"We know that there were kids there using marijuana. We know there were kids there using alcohol," said Satur.

The fight then moved outside where three teenage boys were stabbed aged 19, 18 and 17.

The oldest boy died in the home's driveway.

"They were all acquaintances or friends," said Satur.

Police later arrested 20-year-old Secundino Martinez for stabbing all three victims.

"He was kind of a troublemaker kid in high school," said local Tyler Stone.

Police have not yet released a motive but believe Martinez got rid of the murder weapon after he fled the scene on a stolen bike.

"Right now we are still looking for the knife," said Satur.

Longmont police are still interviewing witnesses, many of whom went to high schools not far from here.

All three victims are from Lafayette.

Police call it an unfortunate tragedy that could have happened anywhere.
.
"It really could have happened at any underage drinking party," said Satur.

One of the two hospitalized victims is now conscious while the other is still in critical condition.

Police have not released the names of the victims.
