Brazilian legislator and television host Wallace Souza speaks Tuesday during a news conference. Brazilian police are investigating Souza on suspicion of commissioning at least five of the murders depicted in his show to boost his ratings and prove his claim that Brazil's Amazon region is awash in violent crime. Police also have accused Souza of drug trafficking and claim that rival dealers were the victims.

SAO PAULO, Brazil — In one murder after another, the "Canal Livre" crime TV show had an uncanny knack for being first on the scene, gathering graphic footage of the victim.

Too uncanny, say police, who are investigating the show's host, state legislator Wallace Souza, on suspicion of commissioning at least five of the murders to boost his ratings and prove his claim that Brazil's Amazon region is awash in violent crime.

Police also have accused Souza of drug trafficking.

"The order to execute always came from the legislator and his son, who then alerted the TV crews to get to the scene before the police," state police intelligence chief Thomaz Vasconcelos charged in an interview with The Associated Press.

The killings of competing drug traffickers, he said, "appear to have been committed to get rid of his rivals and increase the audience of the TV show."

Souza denied all the criminal allegations and called them absurd, insisting that he and his son are being set up by political enemies and drug dealers sick of his two decades of relentless crime coverage on TV and crusading legislative probes.

"I was the one who organized legislative inquiries into organized crime, the prison system, corruption, drug trafficking by police, and pedophilia," Souza said in an interview with the AP.

Souza's lawyer, Francisco Balieiro, said that the only witness is a disgraced police officer hoping for leniency in nine murders in which he is charged.

"There is not one piece of material proof in these accusations," Balieiro said.

Vasconcelos said the accusations, which have made headlines in Brazil, stem from the testimony of several former employees and security guards who worked with the Souzas, allegedly as part of a gang of former police officers involved in drug trafficking.

Souza's son, Rafael, has been jailed on charges of homicide, drug trafficking and illegal gun possession.

Police said Wallace Souza faces charges of drug trafficking, gang formation and weapons possession, but has not been charged with any killings.

Souza remains free because of legislative immunity that prevents him from being arrested as long as he is a lawmaker.

He is being investigated by a special task force, and state judicial authorities will decide whether the case goes forward.

Vasconcelos said the crimes appear to have served the Souzas in two ways: They eliminated drug-trafficking rivals, and they boosted ratings.

"We believe that they organized a kind of death squad to execute rivals who disputed with them the drug trafficking business," he said.

Souza, he charged, "would eliminate his rival and use the killing as a news story for his program."

Souza became a media personality after a career as a police officer that ended in disgrace, according to Vasconcelos, who said the lawmaker was fired for involvement in scams involving fuel theft and pension fraud.

Souza denied those allegations, but said he was forced to leave the force in 1987 after being wrongly accused of involvement in a college entrance exam fraud scheme that he was investigating.
