Unidentified gunmen Tuesday killed a senior government official assigned to track the hidden wealth of exiled president Ferdinand Marcos, police said.

Meanwhile, the military said communist guerrillas shot and killed a suspected military informer in the central island of Cebu and gunned down three civilian employees during a raid on a mining company in Rosario town.Jesus Ronan, 56, a director in the Presidential Commission on Good Government, was gunned down near his house in an ambush in the nearby fishing town of Malabon, police said.

Ronan was driving his car to his office when six men fired on him. Before he died, Ronan stepped on the gas pedal and rammed and injured one of his attackers.

Police said the other assailants picked up their injured companion and fled. Police did not say who they thought was behind the slaying.

Ronan retired as a colonel in the Philippine air force in November and was appointed to the commission assigned to recover the hidden wealth of Marcos and his associates.

Marcos fled to Hawaii after a People Power revolution in 1986. The dictator is facing charges he looted the treasury of billions of dollars during his 20-year rule.
