Family and friends are searching for a 20-year-old National Guard soldier missing since early last week.

Russell Plummer from Cornell is around 5'5'' and 145 pounds with a skinny build. He has a crew cut and brown eyes. He was last seen driving an old yellow Honda Civic from the 1970s, possibly with license plate number 805-NEV.

Dustine Gass says while it's not unlike her brother to spend time with lots of family members and friends, it's very strange that no one has heard from him in more than a week.

"He is always with friends. If he's not with friends, he's on the phone with friends," Gass says.

She says no one has heard from her brother since Monday or Tuesday. The Chippewa County Sheriff's Department says a friend says he was drinking with Plummer at Mornings Corner bar in Bloomer on Monday or Tuesday night.

Investigators also say Plummer has not used his cell phone or his debit card since at least Thursday. He missed National Guard training this weekend and his sister says he was supposed to fill out paperwork to get his $10,000 bonus, but he skipped that too.

"He was very excited about the Guard. He could not wait to go back. He was bored here," Gass says.

Gass says her brother loves to hunt and is always up to something, but has nothing to run away from and never leaves his family out of the loop.

"What's next? He needs to show up. We just want to find him. He can't just disappear," Gass says.

Gass says her brother's friends and family have been searching the Chippewa County Forest the past few days since it's one of Plummer's favorite places.

Investigators entered him into the national computer as a missing person.
