That's all pretty confusing. Katz claims to be robbed out of BTC, while police say his case is not bitcoin-related (?).
Katz lost the following, in addition to getting stabbed:
1. Bitcoin worth some $8,500
2. Fiat cash in US Dollar worth some $3,500
3. His new Samsung mobile phone
4. His credit cards.
As we can see here, the most valuable item was the Bitcoins. Can't understand why the cops announced that his case was not "bitcoin-related".
