PROVIDENCE — In June, two teenagers jostled with members of an Asian youth gang as they passed on a Smith Hill sidewalk. The incident led to the retaliatory shooting of both teens, one fatally, according to the police.

Three teens initially were charged in the crime: A 16-year-old male, who was accused of doing the actual shooting, and a brother and sister, 16 and 13, respectively.

But now the police have dropped all charges against the alleged shooter and are pointing a finger at another 16-year-old male.

The brother and sister recanted their identification of the original alleged shooter, prompting law enforcement authorities to withdraw the charges against that teen, acknowledged Michael J. Healey, spokesman for the attorney general’s office.

Capt. Keith Tucker, commander of the police Youth Services Bureau, said: “The investigation continued, and as more information became available, this new individual was developed as a suspect.”

Given that the suspects are minors, the authorities are withholding their names.

The newly identified suspect is charged with fatally shooting Jeffrey Lopez, 19, who was living with a Federal Hill family, and wounding Carlos Javier, 19, of 145 Camden Ave., Smith Hill, as the victims stood on the front porch of Javier’s duplex.

The new suspect, a longtime resident of Woonsocket who now claims a Smith Hill home address, is charged with murder, assault with a dangerous weapon on Javier, using a firearm in the commission of a crime of violence and carrying a pistol without a license.

The new suspect, who was being held at the Training School for Youth in an unrelated case, has been charged in Family Court. He pleaded innocent and was sent back to the Training School, Healey said yesterday.

As for the brother and sister who were charged, the sister has admitted her role in the crime, according to Healey. She “admitted sufficient facts” — the equivalent of a no contest plea in adult court — and Family Court Chief Judge Jeremiah S. Jeremiah Jr. remanded her to the Training School “until further order of the court.”

That means she can be held until age 19, subject to reviews of her status every six months. It is the most stringent disposition that a Family Court judge can mete out short of transferring prosecution of a defendant to adult court, according to Healey.

The girl was charged with two counts of assault with a dangerous weapon, possession of a firearm by a minor and possession of a firearm without a license.

Her brother continues to be held at the Training School, charged with murder, conspiracy, using a firearm in the commission of a crime of violence, possession of a firearm by a minor and carrying a pistol without a license.

According to the police and the attorney general’s office, after the bumping or jostling occurred, the sister ran into her house and emerged with a handgun. Seeing that, Lopez and Javier left the confrontation and went to Javier’s house, and the girl returned the gun to her house.

But someone else retrieved the gun again, and a small crowd of youths went to Javier’s house, where two shots were fired, allegedly by the newly identified suspect. Lopez was mortally wounded in the neck and Javier was wounded in the back.

Healey said he is unable to specify what the girl’s brother did.

“Given the conflicting versions of events, we are still trying to determine exactly what this respondent’s alleged role was,” he said. “Until we know that answer, the original charges against him will remain.”

The attorney general has asked Family Court to waive the court’s jurisdiction regarding the new murder suspect and the brother so that they can be tried as adults in Superior Court. If waivers are granted, according to Healey, the cases would be presented to a grand jury.
