MANILA: Philippine police searched for an American who escaped after allegedly killing a government official's son in a road-rage shooting - the second homicide case against him, officials said yesterday.

Jason Ivler, 28, from Hawaii, was identified by witnesses as a driver involved in a traffic accident in Manila on Wednesday. It led to a heated argument during which Ivler allegedly chased and shot to death another driver, Renato Victor Ebarle Jr., police said.

At the time, Ivler was driving a car with diplomatic plates owned by his stepfather, Stephen Pollard, an executive at the Asian Development Bank.
