Vinnie Barso is a budding serial killer and incriminator, appearing in Play Dead in CSI:Crime Scene Investigation.


Barso, an ex-con with a rap sheet, had a tumultuous relationship with Carly Green, an ex-prostitute and recovering addict who was turning her life around with the help of K-9 Officer Mike Nelson, who used to work in Narcotics and even personally visited her in prison regularly because he believed she had a second chance. Eventually, Barso got Green pregnant, but he demanded she get an abortion. Scared and not knowing what to do, she met Nelson ten weeks into her pregnancy for support. Barso followed, high on drugs, and fatally mauled Nelson's throat, much to Green's horror, who ran off and left Nelson with his dog Sam, who bit Barso was nearly framed for the crime, but was saved before he could be put down. Not along after Green was identified and she revealed her relationship with Nelson, Barso tracked and confronted her, demanding her to have their baby killed again. When she refused and defied him, he killed her and their baby too with a fatal injection in her back, pricking her arm postmortem to make it look like a suicide. He left her around needles in a bad motel and left his bandage over his infected wound at the scene. He was eventually made when the CSIs tracked him, and when Sam sniffed him out and got his attention by barking at him, he shot at the officers amidst a crowd of bystanders at a food stand, no one getting hurt thankfully. Eventually, he was caught by Sam and his arm was mauled for a bit as a taunt by Nick Stokes before Stokes calls Sam off in his usual French commands. He finds Barso's infected him and has him arrested and given medical attention. It's revealed he shot Sam behind his ear, but the wound wasn't deep and his surgery was successful. Barso eventually confessed in interrogation and was incarcerated for his crimes.
