Police say five strangers showed up after learning about the Brentwood-area party on a social media site.
Investigators say the uninvited people left, but nine people came back later and some of them had knives.
Mitchell William Harkes, 19, of Calgary is charged with second-degree murder, aggravated assault and four breaches of various court orders. A 17-year-old young offender, who cannot be named, has also been charged with second-degree murder.
"It's best not to try to remove them yourself, but contact the police. Have them attend and they'll assist the hosts of the party to remove any unwanted guests," said Staff Sgt. Doug Andrus.
Brett Wiese’s mother, Brenda, says the family is not focusing on the two people charged, but on the loss of their son.
"We're not sitting in anger and judgment and we're not wasting our time on those people," she said. "Right now we have a son to love and a community who wants to be here with us."
Some University of Calgary students agree house parties can get out of hand.
"I don't really attend house parties too much just because I’m afraid of something happening and when too many people are there it can get crazy and dangerous," Stacey Cameron said.

19-year-old appears in court

The 19-year-old charged in Wiese's death appeared in court Tuesday.
Harkes appeared briefly by closed circuit television from the Calgary Remand Centre, but has yet to find a lawyer, so his case was adjourned.
He did not address the courtroom.
Harkes case will return to court next week.
