EDGEWATER, N.J. (AP) _ A Kenyan national killed the son of a former Kenyan diplomat and critically wounded two other Kenyans before he was critically injured in a traffic accident, authorities say.

Sasi Wabuge, 25, was beaten about the head with a tire wrench while he was sleeping at an apartment here Monday, said Bergen County Prosecutor Larry S. McClure.

Wabuge, whose father, Wafula Wabuge, served as Kenyan ambassador to the United Nations from 1982 to 1984, died at Englewood Hospital, McClure said.

McClure identified the suspect in the death as William Bullut, 29, who also lived at the apartment.

Interviews with two of the victims indicated that Bullutt had been acting erratically and was unhappy with being in the United States, McClure said.

According to McClure, after attacking Wabuge, Bullut beat Roy Mati, 25, a visitor from Nyack, N.Y., with the tire wrench and stabbed him with a kitchen knife. A third man, David Kipkemboi, 25, another resident of the apartment, heard the commotion and was able to escape, said McClure.

Bullut then drove about 10 miles to an office where he allegedly stabbed another Kenyan national and apartment resident, Aloysius Makawai, who was working as a security guard, McClure said.

McClure said Bullut then fled to upstate New York, where his subcompact car smashed head-on into a cement truck south of Albany. McClure quoted New York state police as saying Bullut may have purposely driven in front of the truck.

Makawai was reported in critical condition at Pascack Valley Hospital. Mati was in critical condition at Englewood Hospital, according to nursing supervisor Margaret Kloman.

Bullut was in critical condition at the Albany Medical Center Hospital, said Ricard Puff, a hospital spokesman.
