The duo named Jaeger and Ziva are brother and sister German Shepherds from the same litter.
Police say Jaeger made the first arrest Thursday night, helping officers track down a man suspected of attacking his housemate earlier in the day. The man was arrested and booked into jail for investigation of felony harassment. He also was wanted on a drug warrant.
About an hour later, police got a call about a group of people on the roof of a vacant building, bashing a compressor with a sledgehammer. As officers arrived, those suspects ran and hid. Ziva found two people hiding in closets and a third in a roof vent. All three were booked into jail for investigation of burglary.
