INDIANAPOLIS (AP) _ A fired worker shot his boss to death and then turned the gun on himself today, authorities said.

The bodies of the two men were found after police surrounded the Hindostone Products building for four hours and finally blasted open a door and stormed inside. Eight other employees were not hurt.

The plant makes stone drink coasters and silkscreen products.

The gunman was identified as Thanh Le, 31. His victim was Sothy Chim, 25, said Scott Minier, a spokesman for the Marion County Sheriff's Department.

``Apparently when the day shift got in, there was something that was supposed to have been done either last night or the shift prior to this. There was a disagreement between the suspect and the person we feel may be shot at this point,'' said sheriff's Sgt. Dave Wilks.

``There was an argument. The suspect left, was gone out of the building 10, 15 minutes and came back obviously with a firearm.''

Sheriff's Capt. Mike Russo said the man had been fired. After he returned, other employees heard gunshots and fled, Wilks said.

``One person in specific said he looked at her, pointed the weapon down ... and stuck his hand up and said `No,' that he did not want her,'' Wilks said.

``And he had plenty of opportunity to shoot her. But he did not. He was after his target, which is the person who we feel has been shot at this point.''

Police heard more gunshots from inside after they arrived. A SWAT team set up around the building and authorities sent an Vietnamese interpreter close to the building in an armored car to call to the gunman via a loudspeaker. There was no response.
