SAN JOSE, Calif. (AP) _ A woman rode a bicycle over a newly poured church sidewalk, setting off an argument that ended with blasts from a Uzi semiautomatic gun that left one man dead, according to police.

Etualie ''Eddie'' Laufasa, 48, was pronounced dead in the emergency room of San Jose Hospital after the shooting on Monday. A companion, Tino Matuu, was listed in critical condition with gunshot wounds in the thigh and cheek.

The two men were shot outside Most Holy Trinity Church where they had volunteered to pour concrete.

Police arrested the bicyclist's brother, Jonathan T. Tolentino, 29, on charges of suspicion of homicide and assault with a deadly weapon.

Police said Laufasa and Matuu, both parishioners at the church and members of the Samoan choir, argued with Nannette Canillas when she rode her bicycle across the fresh concrete.

The woman's husband, Emiliano Canillas, confront the men a few minutes later, police said. After at least one punch was thrown, a bloodied Canillas returned home. Shortly after, the shooting occurred.

Police Sgt. Randall Spitze said that a car parked in front of the church and registered to the Tolentino family contained a case big enough to carry the gun used in the shooting, a magazine article about Uzi guns, a pistol in a holster and a police scanner.

Investigators later brought a large white box marked ''Uzi'' out of the Tolentino home.
