A 19-year-old man has been charged with murdering an aspiring actress when she confronted a group of men during a holdup.

Rudy Fleming was arraigned Tuesday on charges of murder, robbery, attempted robbery and weapons possession, said Assistant District Attorney Robert Hettleman. If convicted, Fleming could face up to life in prison and possibly the death penalty, Hettleman said.

Nicole duFresne (search), her fiance and another couple were leaving a bar in a section of Manhattan's Lower East Side (search) known for hip nightspots early Thursday when they were approached by four or five men, one of whom demanded money, police said.

Witnesses said one of the men grabbed for the other woman's purse and duFresne intervened, asking: "What are you going to do, shoot us?"

One of the men then fired a shot, police said.

Fleming and four others were picked up for questioning late Sunday, police said. Two of the four were charged in an attempted robbery the same night but not in duFresne's slaying, and the remaining two were considered witnesses, police said.

Police said the murder weapon — a .357-caliber revolver (search) — was found in the home of one of Fleming's relatives.

Fleming's attorney, Dennis Murphy, did not immediately return calls for comment.
