The Lion Man's sister has lodged a police complaint alleging she has been unable to remove two $30,000 horses and other items from Zion Wildlife Kingdom.
Megan Busch said two horses valued at $60,000, two saddles, a briefcase containing a horse clipping unit, assorted horse items, a quad bike and a horse trailer are at the park, but she can't get them back.
However, the park's new co-owner Ian Stevenson said both Patricia and Megan Busch had been asked to provide proof of ownership of any personal items at Zion, but had so far declined to.
Mr Stevenson said the items could belong to another party and it was appropriate to be careful and confirm clearly who paid for them before determining ownership.
He said the park considered the matter closed.
