Police say Berta Pereira-Roldan, of Revere, was not the intended target of the shooting on Detroit Avenue. “This is a tragic weekend for our city,” Providence police Maj. David Lapatin said Monday.

PROVIDENCE — A Massachusetts woman celebrating her 19th birthday was shot and killed early Sunday after leaving a city nightclub, police said.

Police say Berta Pereira-Roldan, of Revere, was not the intended target of the shooting on Detroit Avenue. Another person described by police as innocent bystander, 38-year-old Crystal Peloquin of North Providence, was also shot and injured.

Peloquin's injuries are serious enough to require surgery but not believed to be life-threatening, police said. Peloquin and Pereira-Roldan were not together late Saturday night and early Sunday morning, but both had been at one of two Broad Street clubs that share a building, police said. The clubs are Levels Lounge and Noah Lounge.

Two other men with whom Peloquin was speaking after leaving one of the clubs may have been the targets, Maj. David Lapatin said. Pereira-Roldan was several houses down, outside 15 Detroit Ave., police said.

“This is a tragic weekend for our city,” Lapatin said Monday.

Anyone with information about the homicide should call Detective Teddy Michael at (401) 243-6302. The two men who police believe may have been the targets of the shooting have possible gang associations, the police said. They’ve spoken with police, but Lapatin declined to go into details about what they said.

Police said the shots were fired from the area of Niagara Street, down Detroit Avenue toward Broad Street. Pereira-Roldan was with a few friends closer to Broad Street when the shots were fired, police said.

On Monday, a small memorial with a burning candle, a flower and a teddy bear was on the curb along Detroit Avenue. Pereira-Roldan had recently graduated from Revere High School, according to a story in the Revere Journal.

Club patrons use Detroit Avenue to park, Lapatin said. Police could not say whether the shooting stemmed from a dispute inside the club, but Lapatin added that the two women who were shot “were not bothering anyone” and were simply getting to their cars to leave.

“When nightclubs close, get in your car and go home,” Lapatin said. “Don’t hang around the outside of these clubs.”
