NEW YORK (CBSNewYork) — An 18-year-old accused of killing his mother’s ex-boyfriend appeared in a Bronx courtroom Friday.

Police say high school football player Luis Moux strangled 43-year-old Stanley Washington early Monday morning.

His lawyer says the teen was defending his mother from being attacked by Washington, who had a long history of arrests for alleged domestic abuse.

“This is an 18-year old victim,” said attorney Walter Fields. “Some animal tried to hurt his mother and he did what any good, young man would do.”

Moux is facing a manslaughter charge and is out on bail.

A grand jury will decide if he goes on trial.
