An assistant chief with the Grantsburg, Wisconsin Volunteer Fire Department died Monday of injuries he suffered in a Sunday fire and building collapse.

Dana Johnson, 46, was trapped when the roof of a building housing a restaurant and antiques shop collapsed, pushing the walls outward onto firefighters. Also trapped and injured was Firefighter Derek Zeiler, also with the Grantsburg VFD.

The fire began as the result of a domestic dispute. Burnett County Sheriff's Deputy Chris Sybers said Duane Barnes, 41, took his wife to work at the Sunshine Restaurant. When he left, he set fire to the building and shot out the tires of her truck.

The wife reported the fire at the sheriff's office and deputies responded to the restaurant. They also called the Siren VFD. Not knowing where the husband was, the deputies had to keep the firefighters away from the fire for almost an hour until they secured the building. The husband was found dead about a half-mile away of a self-inflicted gunshot wound.

By the time firefighters were able to attack the fire, they left with exterior defensive tactics only since the fire was in an advanced state. The collapse of about 40 feet of roof came suddenly and Johnson and Zeiler were caught while trying to move away.

Deputy Sheriff Sybers who is also a Siren volunteer firefighter and EMT, said they had to use jacks and airbags to raise the wall from Johnson who was completely buried, which took about 10 minutes. Sybers traveled with Johnson to Burnett Medical Center in Grantsburg doing CPR and said they had a heartbeat in the emergency room.

Johnson was transported to North Memorial Hospital in Robinsdale, Minnesota where he died on Monday.

Also injured in the fire was Siren VFD Firefighter Ron Morse who was knocked from a ladder when the roof collapsed. He and Derek Zeiler were treated at the hospital for their injuries and released.

Johnson was married with three children. The oldest child is married, and the younger ones are 12 and 15 years old.

He worked nights at a manufacturing company, and after his shift he would come to the fire hall for a few hours to take care of any work that needed to be done, such as shoveling snow or administrative duties, said Grantsburg Fire Chief Terry Peterson.

"He was a very happy individual. He always had a smile on his face, and we never heard him say an unkind word about anybody," Peterson said. Service arrangements will be reported as they become available.

A fund has been established for Dana Johnson's family at FirstStar Bank, P.O. Box 69 in Grantsburg, WI, 54840.

Siren in Burnett County is in the northwest section of Wisconsin, near the Minnesota border.
