BEVERLY — A man was shot to death at a home Saturday night, and a local teenager turned himself in to face murder charges, authorities said.

Justice Galarza, 19, surrendered to police in nearby Salem on allegations that he shot and killed a 21-year-old man whose identity has not been released.

The shooting took place at about 10:30 p.m. in a residence on Ropes Street, according to the Essex district attorney’s office.

The men appear to have known each other, according to Carrie Kimball-Monahan, a spokeswoman for the prosecutor’s office.

On Sunday afternoon, children played on swings and slides at a playground near the triple-decker house where authorities said the shooting occurred.

One of the families there declined to comment.

A group of five young men on an adjacent street said they were good friends with Galarza but did not know the victim.

“He’s not a killer,’’ said one man, who gave his name only as “M.’’

He described Galarza as a “good kid.’’ who took care of his grandmother.

Another man said the residential neighborhood used to be rough years ago but had become much nicer.

Galarza, who authorities said lives on Beckford Street a few blocks away, is set to be arraigned Monday in Salem District Court.

The shooting remains under investigation by Beverly police and State Police.
