GOIANIA, Brazil — Police on Thursday accused a Brazilian man of killing and dismembering his 17-year-old British girlfriend, taking pictures of her body parts with his cell phone and stuffing her torso in a suitcase.

Goias state police inspector Jorge Moreira da Silva said officers found the suitcase with the torso of Cara Marie Burke on Monday at the edge of a river in the central Brazilian city of Goiania.

Burke's boyfriend, Mohamed D'Ali Carvalho Santos, 20, was arrested on Thursday and was charged with homicide, Silva said.

"He confessed he cut her up and even photographed the body on his cellular phone," Silva said from Goiania, about a two-hour drive from the capital, Brasilia.

He said Santos killed Burke because she threatened to tell his parents he was a drug dealer addicted to cocaine, and she was considering turning him in to police.

Burke, who had been in Brazil about three months, was stabbed to death on Saturday and dismembered on Sunday, the police inspector said. The two met when Santos was living in London, where his mother also lives, and Burke had visited Brazil before, Silva said.

Friends of the victim identified the body from a tattoo on the girl's torso.

Police were still searching for Burke's head and limbs, which Santos said he hid in a rural area about 20 miles (30 kilometers) outside Goiania. Santos was taken by police in handcuffs to be filmed by television crews, but held his head down and said nothing.

Karine Neves, a spokeswoman for the British Embassy in Brasilia, said she did not have more information about what Burke was doing in the country.

Neves said a British vice consul is in Goiania tracking the case and the police investigation.

Burke's online acquaintances posted messages on her Orkut Web page demanding justice for her killing. Orkut is an online social networking community hugely popular in Brazil.

The page also featured pictures of the blond teenager posing with friends in London and Brazil and holding a baby in her arms.
