Here's another article from the Inter-County Leader, which also covers the area. The info from the article looks to be a couple hours out of date, with no updates so far, but additional details are included, most notably that the poor girl who was killed was a resident of Hinckley, MN:

Sheriff asks nonresidents to stay away from damaged areas BURNETT COUNTY - At least one person is reported dead and several others injured following devastating thunderstorms that ripped through northwestern Wisconsin Friday evening, producing 100 to 110-mile-per-hour winds.
The Burnett County Sheriff's Department reported that an 11-year-old Hinckley, Minn. girl was killed when a tree fell on her at Scenic View Campground on Poquette Lake, about 15 miles east of Siren. There was a second death - a man who suffered a heart attack - initially thought to have been related to the storm but authorities said Saturday afternoon it was not related.
Three persons were critically injured due to the storm, according to Burnett County Sheriff Dean Roland. He said 39 people were known to be injured in the storm, which affected three-fourths of the county's geographical area. Roland said the situation occurred during a holiday weekend when Burnett County sees its population swell from 17,000 to 80,000 people - plus those who came to Wisconsin in light of the shutdown of Minnesota's state parks - and those people are experiencing a lot of frustration as their holiday weekend turns to one of dealing with property damage,loss of electricity and long gas lines.
He asked that nonresidents stay away from the damaged areas. Most of the damage, Roland said, occurred from the west side of Yellow Lake northeast to Birch Island Lake.
The village of Grantsburg is shut down as authorities worry about gas leaks from uprooted trees.
All ATV trails in the county are closed and may be closed for weeks, Roland said.
I know that campground pretty well, and before the storm there would have been no sky visible from that location — only trees.
