After a teenager tragically died in Lake Tahoe over New Years, the girl's family helped launch a new campaign for young people to buddy up.

Nineteen-year-old Alyssa Byrne froze to death along a South Lake Tahoe road over New Years when she left her friends at a concert and tried to walk back to their hotel. They'd all been partying and her friends didn't report her missing until the next day.

A benefit concert will be held Saturday night at the Phoenix Theatre in Petaluma and wristbands that say, "Always Buddy," will be sold at the event as a way to fund a new public safety campaign.

Alyssa's friend Jay was on the Tahoe trip and he organized the benefit concert to print teaching materials so older teens can counsel younger ones about having a buddy and being a buddy.

Alyssa's parents Kevin and Kim Byrne are hoping parents also ask their children who they are buddying up with.

"When Alyssa left, if somebody had gone with her they could have realized they were going the wrong direction," said Kevin Byrne. "We want them to be together; we want them to not leave somebody off by themselves and know when they go out in a group, that's their responsibility, being with that other person."

Alyssa's friend Taylor Derby came up with the idea for the wristbands.

"Now, it should be an automatic thing when we're out," Derby said. "Never be alone, never."

Derby said they already sold 300 wristbands this week.

The Byrnes don't blame their daughter's friends. In fact, they're closer than before. Kevin Byrne said he regrets not realizing the concert was a rave where recreational drug use was widespread.

"I didn't take the time to research it, that's on me, and I hope other parents look in on that before they let their kids go to an event like that," he said.

Meth was found in Alyssa's system, he said, she would never have taken it knowingly.

"In talking to some of the kids who were up there, they didn't know what they were buying," Kevin Byrne said.

"Somebody can give you something and say what it is, but there's no way for you to know. "

Byrne's hoping the always buddy program will debut in local schools this spring.
