Sergeant James Doakes and Detective Angel Batista were able to build a decent manslaughter case against Rodrigo. Unfortunately, Dexter Morgan had other plans and intentionally screwed the blood work up so he could have Rodrigo to himself. He was later killed by Dexter with a cordless reciprocating saw.
Debra and Angel Batista question Rodrigo's paranoid neighbor, and collect his notebooks. They learn that Rodrigo was carried out of his home by an unknown man, and placed in a car on 16 April 2002. They look up the license plate, and discover that it was on a car being held in police evidence at the time.
