You may remember the fight back in July.
The mother of the robbery suspect said her son may file a lawsuit. She said the good Samaritan, 58-year-old Cregg Jerri, used excessive force when he overpowered her son with a chair and used the suspect's own knife to disarm him.
"The guy, in my opinion, went from a Good Samaritan to a vigilante," suspect's mother Pamela Chimienti said.
Investigators said Jerri was stabbed in the neck during the struggle but managed to wrestle away the knife and stab the suspect several times.
The suspect survived and is due back in court next month.
