Chelsea police say they have made an arrest in connection with a shooting that left a 68-year-old woman hospitalized last week.

Jefferson Barrillas, 18, of Lynn pleaded not guilty to multiple charges, including armed assault to murder, in Chelsea District Court on Wednesday.

Emergency crews were called to the scene near a Silver Line stop on Washington Avenue around 1 p.m. Friday for reports of the shooting, according to a release issued by the police last week.

Upon their arrival, police said they found five shell casings littering the street and the 68-year-old woman was already on her way to the hospital. Police caught up with her on Everett Street and escorted her the rest of the way to Massachusetts General Hospital where she is being treated for a serious chest wound.

Officials say she is home now and doing well.

A day after the shooting, police said they tried to pull him over but he took off and struck an officer with the car’s side-view mirror in the process.

That officer was treated at the scene and returned to work immediately after.

Suffolk County District Attorney, Kevin Hayden said this careless act of violence is unacceptable.

“A 68-year-old woman going to get her taxes done should never be subject to the sort of situation where she finds herself in an incident that, as she described, her life changed,” he said.

No further details have been released.
