(CNN) -- A man has admitted he killed his uncle's 6-year-old stepdaughter, whose body was found in a Louisiana trash can this week, a spokesman for the Jefferson Parish Sheriff's Office said Wednesday. 

Matthew Flugence admitted to detectives Wednesday morning that he stabbed Ahlittia North, a girl he previously babysat, over the weekend, Col. John Fortunato said. 

Flugence, 20, was arrested in the case on Tuesday, the day authorities found Ahlittia's body in a trash can down the street from her mother and stepfather's apartment in the New Orleans suburb of Harvey. 

Flugence, who had an outstanding warrant charging him with sexually assaulting an 11-year-old girl last year, has been charged with murder in Ahlittia's death, Fortunato said. 

"I don't know what I else I can say about the character of an individual that just admitted to killing a 6-year-old," Sheriff Newell Normand told reporters Wednesday morning when asked about Flugence's background. "I think that speaks for itself." 

Flugence's brother Russell, 21, was arrested on suspicion of obstructing justice in Ahlittia's death, Normand said earlier this week. Russell Flugence had information about the crime that he didn't come forward with, and he also had information implicating his brother, the sheriff asserted. 

Matthew Flugence told investigators that he killed Ahlittia after finding her early Saturday outside the Harvey apartment where her mother and her stepfather -- Flugence's uncle -- lived, Normand said Wednesday. 

"(Flugence's) story is (that) in the early morning hours ... he happened to see her out and about, and he was out and about, walking through the neighborhood," Normand said.
