CARACAS, Venezuela - The chief of Venezuela's criminal police say the discovery of a digital camera stolen from the popular actress Monica Spear and her ex-husband was key to identifying the seven people arrested in their fatal shooting.

Commissioner Jose Gregorio Sierralta says the camera was found during a search of the home of one of the people arrested for the killing of the pair on an isolated stretch of highway Monday night during a robbery.

Their deaths have triggered a national uproar over Venezuela's rampant violent crime.

Sierralta says the camera led police to a criminal band that preyed on motorists on the section of highway near Puerto Cabello, the country's main port. He says at least 11 people took part in the crime and four remain fugitives.
