If you have been the victim of a crime, you have the right to seek civil justice against the person who harmed you. For example, drunk drivers who cause collisions are legally responsible for the harm resulting from their crimes.
You may also be able to claim compensation from a negligent third party whose actions or failures to act allowed the crime to occur. For example, landlords or property owners are generally required to exercise care in keeping the premises safe for visitors. If a property owner ignored security violations in the past, that owner may be liable when poor security enables a criminal offender.
Unfortunately, even if the offender has been arrested and prosecuted, the insurance company may deny your claim or resist paying for your medical expenses. Consult an attorney who has experience holding criminals and insurance companies accountable.
