As families of the victims of the stage collapse at the Indiana State Fair are still struggling to come to terms with the tragedy, others are preparing to fight back in court.

The first lawsuits were filed Friday by a Northwest Indiana law firm seeking tens of millions of dollars from the handful of companies that hosted the Sugarland concert at the Hoosier Lottery Grandstand, reports IndyStar.com.

The initial multimillion dollar lawsuits are on the behalf of Janeen Beth Urschel, 49, of Wanatah, Indiana, whose partner of ten years, Tammy VanDam, 42, was killed in the collapse as the couple attended the concert together.

Attorney Kenneth J. Allen explained that the filings are just a drop in the ocean in what will become an increasingly complex legal case.

"This was a terrible tragedy that could and should have been prevented. The responsible parties must be held to account," said Allen.

The attorney is seeking $50 million for VanDam's estate and $10 million plus punitive damages for Urschel from the numerous companies involved in the concert, which included Mid-America Sound Corp. of Greenfield, which owns the stage rigging structure; Live 360 Group, the show's Indianapolis-based booker; and Live Nation Entertainment, owner of Ticketmaster.

Along with lawsuits filed Friday, Allen also plans in the near future to challenge Indiana law's lack of recognition of a same-sex partner as a beneficiary under its wrongful-death law, and seek damages from the state for the victim's 17-year-old daughter.

As RadarOnline.com previously reported, the tragedy occurred during the Indiana State Fair on August 13 as thousands of fans were waiting to see Sugarland perform.

Five people were killed immediately.  A sixth victim, Jennifer Haskell, a student at Ball State University, died from her injuries on Friday.

The death toll from last week's Indiana State Fair grew to six Friday morning when Jennifer Haskell, a 22-year-old Ball State University student, died at an Indianapolis hospital, according to her uncle Mike Whited.

Haskell, who was majoring in sports medicine, suffered what would turn out to be fatal injuries when high winds of 60-70 mph caused a stage to collapse, killing six people and injuring more than 45 others.
