It's likely you're thinking of "suicide ganking", where the attacker is destroyed by police but still turns a profit due to the loot their partner can take from the victim.
You also mention ships capable of preventing warping. Those ship can only be used in "null sec" space, where there are no police ships. And even if they could be used in "high sec", preventing warping would not prevent a pirate from moving up to a target using normal engines and destroying them.
