At the station, Lundy and Angel are talking algae to the task force. Apparently, the algae from the rocks have high levels of zinc and lead, and there are only three marinas that have the kind of restricted water flow that would lead to such high levels of those specific pollutants. "Turkey Creek, Sunset Keys, and Corral Cove," says Angel. "Anyone familiar with these marinas?" asks the Lundster. Deb mentions that Corral Cove is where Harry kept the family boat, and where Dex keeps his now. Angel mentions that it's one of the few marinas left "that's still affordable on a cop's salary." Lundy announces that he and Deb are going to work the Corral Cove, and assigns the other marinas to other cops.

"Sorry it took so long," says the file clerk to Dexter. "I couldn't seem to find any of the crime scene files. Probably lost in storage somewhere. Anyway, that's what I was able to dig up." Dexter asks if she's sure it's just one file: "There were three men arrested for those murders." "Well, one's deceased, one's doing life without possibility...that's the only one that's still an open case. Santos Jimenez." Dexter asks why the case is still open, and the clerk tells him it's because Jimenez went into witness protection. "There's a business address in there for him. I guess after thirty-four years, he figures all the people who want him dead are long gone." "He figured wrong," Dex VOs. The clerk mentions that there are also some audio tapes cross-referenced with the file, if Dexter wants those, too. "Tapes?" "Yeah, there was a criminal informant working the cocaine bust from the inside."
