'My Uncle Killed a Guy') is a 2004 Brazilian crime comedy film co-written and directed by Jorge Furtado.

It follows the adventures of 15-year-old Duca (Darlan Cunha) and his two friends after his uncle, Eder (Lázaro Ramos), confesses to his family of having shot a man.

However, Duca suspects that his uncle's story about killing his lover's ex-husband in self-defense is not entirely truthful and so sets out to solve the mystery.

Duca sees Kid touch Isa's shoulder, though, and becomes jealous so he decides to return home.

They relay the message, to her general disinterest, and she requests that Duca repair her automatic pool cleaning device—a product of Eder's that failed to sell well.

Moving inside, his suspicions are confirmed when he sees a tattooed male arm answering a phone downstairs.

While leaving, they accidentally track soil from a broken vase over the carpet downstairs to the fury of the doorman.

He believes that Eder would never take Duca's word for it about the man living with Soraya, and so he goes about hiring a private investigator to obtain photographic evidence.

The series of pictures seems to suggest that the two had sex, and when Isa asks to see the photographs, Duca refuses to show them, causing yet another fight between the two friends.

Duca mails the photographs to Eder, hoping it will convince him to tell the truth to the police, and he remains not on speaking terms with his two friends for nearly a week.
