Luca Russo is an agent of the Italian authorities and a contact of Agent Phil Coulson of S.H.I.E.L.D. He betrayed Coulson's Team to Ian Quinn and Cybertek, who had him on their payroll for their smuggling operations, and was killed for this by Agent Melinda May.
Working with Phil Coulson
During a mission to locate Ian Quinn, Agent Phil Coulson requested the help of Luca Russo, one of his contacts in Europe, to help his agents in an undercover mission to board a train that was crossing the Italian countryside carrying a package from Cybertek that Ian Quinn recently purchased.

"You called me 'sweetheart'."

Russo betrayed Coulson's Team and informed of their plan to Cybertek's security agents, led by Carlo Mancini. When Agent Melinda May fell from the train, Russo and his men captured and tortured her for information in a nearby barn.
Coulson, unknowing Russo's betrayal, contacted him. Russo went to The Bus with the intention of killing agents Coulson and Grant Ward. Melinda May's timely arrival prevented Russo's plans, as he was killed with a throwing knife in the back.
