What case shows how the exclusionary rule works?

Can you find a case where evidence obtained by a security guard, bounty hunter etc. was used to convict?

I need 2 cases that show how the exclusionary rule (evidence obtained by a person who is not law enforcement is admissible in court even if it's an illegal search since it wasn't done by a cop) was used to convict a person of a crime.

I'm studying the case of Burdeau v. McDowell and how the U.S. Supreme Court ruled any incriminating evidence that is obtained during an illegal search by any non-law enforcement private party, security officer, bounty hunter and the like, is admissible in criminal and civil court.
