The man accused in the triple murder shootings in Pennsylvania was charged Sunday in New Jersey.

Authorities say 26-year-old Andre Gordon is facing carjacking counts and numerous weapons charges. The Bucks County District Attorney’s Office said Gordon's first scheduled court date will be in New Jersey, but it was not aware of a date for extradition back to Pennsylvania. It said it could take a few weeks until he is returned to Bucks County.

The Bucks County District Attorney’s Office released the docket of the charges against Gordon.

Police say Saturday’s events began with a carjacking in Trenton. They say he then fled to Pennsylvania where he fatally shot his stepmother, sister and mother of his children. Another woman was injured after Gordon "bludgeoned" her with an assault rifle, police say.

They say he then stole another car and returned to Trenton where it was believed he barricaded himself inside a house on Phillips Avenue. Gordon managed to leave that house unnoticed before police finished setting up a perimeter. He was found walking on New York Avenue.

Attorney General Matthew Platkin releasing a statement following the charges announcement:

Gordon was processed at the Trenton police station. He was being held as of Sunday night at the Mercer County Correctional facility pending a hearing to move him to Pennsylvania.

According to the Platkin:

"Gordon was charged by New Jersey authorities with first-degree carjacking, second-degree possession of a weapon for an unlawful purpose, second-degree unlawful possession of an assault firearm, third-degree unlawful possession of a firearm without a serial number, third-degree receiving stolen property, fourth-degree unlawful possession of large-capacity ammunition magazines, and fourth-degree possession of hollow-point ammunition."
