Kelowna teen apologizes for party left home trashed

A Kelowna teen who organized a party that left his home trashed is issuing a public apology.

Andrew Mann’s parents left him in charge of their Upper Mission home when they were away on a ski trip last weekend.

The 17-year-old posted details about the party on Facebook, and nearly 100 people showed up at the house on Saturday night.

Some party-goers smashed windows and furniture, destroyed carpets and stole valuables. The damage is estimated at $20,000.

Mann says his entire family is angry with him — even his grandmother.

“My grandma was like, ‘What was the whole disaster about?’ And she was like, ‘Andrew you're a jerk.’”

Mann says he's learned a lesson about respect.

“I obviously had no respect for my dad when I threw this party,” he said.

“If I respected him I wouldn't have thrown this party. I would have been a little more considerate. So I obviously didn't respect the guy enough to keep the party from happening."

Mann says he didn't witness the majority of the vandalism. He is cooperating with the police officers investigating the incident.
