16-year-old kills 20-year-old at a party in St. Cloud, Minn.

20-year-old Davee Duvose lost his life early Friday morning after being stabbed by a 16-year-old at a St. Cloud house party, and he was just trying to protect his friend Chelsea Siegle.

“I was nonstop crying,” Siegle said.  “I didn't sleep for three days after that.  He took care of everybody else before himself.”

The St. Cloud student was killed after he stepped in to protect Siegle from a violent stranger.  Siegle, her girlfriends, and Duvose were at house party in St. Cloud when she was approached.

“One of the dudes came up to me and was asking me what's your name what's your number, you're cute,” Siegle said.  “And I said ‘no I'm good. Can you just leave me alone?’ And he was like, ‘you're a bitch.’ I was like ‘excuse me?’”

16-year-old Muhiyadim Mohamed Hassan randomly jumped into the brawl with a kitchen knife after Duvose began protecting Siegle. She said Hassan just "came out of the blue and stabbed Davee."

Everyone who knew Duvose seems to describe him the exact same way – as the “brother” and a peacemaker.

“He has a big brother instinct even though he's much younger than me but he's always been like that with everybody,” Karen Garth.

Duvose's mother Sylvia is comforted to see how much her son was loved.  Her only hope now is that his killer is brought to justice.

“I hope everybody learns from what happens,” Sylvia said.  “I feel it's something positive you can get from everything.”

According to the criminal complaint, after initially lying, Hassan ultimately came clean to police.

Hassan faces a second-degree murder charge and could very well be tried as an adult. Meanwhile, Duvose’s funeral takes place July 17.  The family is seeking support laying Duvose to rest -- you can find his GoFundMe page and funeral details here.
