The documents also state Klitschko 'has been informed that certain items of personal property belonging to Hayden, including jewelry, have disappeared or remain unaccounted for.'Some items are currently in the custody of law enforcement in connection with the ongoing investigation.

The former couple met at a book launch in 2009. After two years of dating, they split up in 2011, before rekindling their relationship two years later. In October 2013, they were engaged, with the actress giving birth to their daughter, Kaya, the following December. However, it was confirmed in 2018 that the couple had split again but remained on amicable terms. Later that year, Panettiere announced she had made the 'difficult decision' to sign full custody of Kaya to her ex.The widely discussed move came after Panettiere fell into a deep depression, which she said made her 'feel nothing', and led to her 'turning to wine' and ultimately being sent to rehab for both depression and substance abuse.

I was going through a really challenging time in my life.'
