|Minor Character: Las Vegas|
|Name||Syd Booth Goggle|
|Pathology|| Serial Killer|
|Portrayed By||Michael Cerveris|
|First Appearance||Strip Strangler|
He begins by murdering Audrey Hayes, however it just looks like a one off murder until he moves on to his next victim, Eileen Snow and then onto Tracey Berg in her apartment. This murder has the same features as the murder of Audrey and Eileen, which leads everyone to believe there is a serial killer on the loose. So the FBI is called in, much to the disapproval of the CSIs, especially Grissom. Syd goes to the crime scene as he is the security guard at the apartment and he feigns innocence and even offers to help Grissom.
After the FBI did an unsuccessful attempt of luring him out using Sara as bait, another man copies Syd's signature in a murder to cover up the fact he killed his wife. Though the FBI charge him with the real Strip Strangler's murders, Grissom doesn't believe he did all of them since the scene was staged. Grissom decides to take the case into his own hands after Sheriff Mobley pulls him off the case for suggesting to a journalist that the suspect in custody is not the killer.
This eventually leads Grissom to suspect Syd and goes to check his apartment, after following a trail he finds Syd in the apartment's basement. Grissom tells about the evidence he found in the trash, leaving it in a public area. He informs Goggle that the lab would be able to match the towels he used to gag his victims to a fiber found in a victim's throat. Realizing he'd been caught, Syd picks up a nearby wrench and hits Grissom, then he picks up a shovel and raises it above his ready to kill Grissom, until Catherine bursts in and shoots him several times in the chest, killing him.
Goggle targeted tall female brunettes who worked out at the same gym as him. After stalking them for some time, he would break into their houses at night while they slept and attack them, first beating them into submission with an improvised weapon from the scene, then forcing them to drink sodium amytal, gagging them with one of his gym towels, undressing them and then torturing them by choking them repeatedly, resucitating them each time, and raping them repeatedly with an object from the scene before finally killing them by strangling them with some ligature from the scene. He would then pose the bodies to make the victims look like pinup girls.
Goggle would also take several counter-forensic measures, such as wearing latex gloves, shaving his entire body to avoid leaving behind hairs and wearing a toupé in case the victim grabbed his hair. He would even go so far as to plant semen he obtained from another man. After each killing, he would also vacuum the crime scene with a vacuum cleaner from the house and take the bag with him.
