An American man and four members of his household were shot dead at his rented home in Pampanga Thursday, police said. Albert Mitchell, a retired US Air Force man, was attacked along with his wife, Jeanette Androneda, househelpers Isabel Fajardo and Marissa Prado, and a man identified Boy Vergara. The American and his family lived in the house inside the gated community in Angeles City, about two hours' drive north of Manila, police said. Police are looking for a lone suspect, a man who had visited Mitchell earlier Thursday before the bodies were discovered by a security guard at the housing enclave, said the city police chief, Superintendent Danilo Bautista. Initial investigation revealed that the suspect entered the subdivision at around 12 noon and went out carrying several items. Security guard Angelito Prado, brother of one of the victims, Marissa, discovered the bodies with gunshot wounds from a 9-mm pistol. Prado told police he had asked a fellow guard not to allow the man to leave the subdivision while he checked on Mitchell's house, just 50 meters away from the guardhouse, as he suspected something was wrong. Prado rushed back to the guardhouse after discovering the crime, but the suspect was already on board a tricycle. The suspect got off at the nearby Marisol village, according to the tricycle driver, but police authorities were unable to track him down. Police recovered on the scene a white sack containing some of Mitchell's belongings including a wallet, computer accessories, and a DVD player. According to Bautista, it appears that the victims knew the lone suspect as there were no signs of forced entry. “Scene of the crime operatives are presently conducting crime scene investigation. Manhunt operation is being conducted by our office,” Bautista said.
